Auckland’s weather is the single biggest factor that will shape your trip. Get it right and you’ll be swimming at black-sand surf beaches, sipping wine at island vineyards and exploring volcanic hilltops in T-shirt weather. Get it wrong and you’ll be ducking horizontal rain showers in a CBD doorway, wondering why your “summer holiday” needs a fleece. The good news: Auckland’s oceanic, sub-tropical climate is genuinely mild year-round — there’s no real off-season — but each month has its own personality.
This complete Auckland weather guide walks you through every month of the year — temperatures, rainfall, sunshine hours, sea temperatures, what to pack, what to do, what to expect — so you can plan a trip that actually matches the weather you’ll get. We’ve cross-referenced NIWA climate data, Auckland Transport seasonal advice and on-the-ground experience to bring you the most useful month-by-month breakdown anywhere online.
Auckland weather at a glance
Auckland sits at latitude 36.85°S — roughly the same distance from the equator as Sydney or Los Angeles, but with a very different feel. The city is wrapped on three sides by water (the Tasman Sea to the west, the Hauraki Gulf to the east, the Manukau Harbour to the south), and that ocean influence dominates the climate. There are no cold continental winters and no scorching summers — just a perpetually mild oceanic climate that locals call “four seasons in one day”.
- Climate type: Oceanic / sub-tropical (Köppen Cfb)
- Annual average temperature: 15.6°C (60°F)
- Warmest month: February — average high 23.7°C, low 16.3°C
- Coolest month: July — average high 14.7°C, low 7.9°C
- Wettest month: July (147 mm rainfall, 14 rainy days)
- Driest month: February (75 mm rainfall, 10 rainy days)
- Sunshine hours: 2,060 per year — one of New Zealand’s sunniest cities
- Sea temperature range: 14°C (Aug) to 22°C (Feb)
- Frost: Rare in central Auckland; occasional in outer southern suburbs
- Snow: Effectively never (last meaningful CBD snow: 1939)
Two practical takeaways: it’s never very cold, but it does rain a lot — Auckland averages 1,210 mm of rainfall a year, more than London (601 mm) or Sydney (1,213 mm). Showers are usually short and sharp, not all-day soakers. Always pack a light rain layer, even in February.
Auckland’s four seasons (Southern Hemisphere)
Remember: Auckland is in the Southern Hemisphere, so the seasons are flipped from Europe and North America. December–February is summer; June–August is winter. New Zealand also observes daylight saving from late September to early April — so summer evenings stretch to 9pm, while winter nights start at 5:30pm.
Summer: December to February
This is peak season — long warm days, the sea is finally swimmable, and the city empties out to the beaches. Highs of 23–25°C, lows of 15–17°C, sunshine hours of 7–8 per day, and sea temperatures peaking at 22°C in February. Humidity climbs into the 70s and 80s on muggy days, particularly January, but ocean breezes keep everything comfortable. Expect occasional thunderstorms and sub-tropical downpours, especially late afternoons.
What to do: swim at Mission Bay, Cheltenham, Takapuna or the wild west-coast beaches; ferry to Waiheke for wine; ASB Classic tennis (early January); Auckland Anniversary Day Regatta (last Monday of January); Music in Parks and Movies in Parks free events.
What to pack: shorts, T-shirts, sundresses, two swimsuits (one always drying), a light jumper for evenings, sunscreen SPF 50+ (UV index regularly hits 9–11 — extreme), sunglasses, a wide-brim hat, and a fold-away rain jacket. The Kiwi sun is unforgiving — the ozone hole effect makes UV roughly 40% more intense than at the same latitude in the Northern Hemisphere.
Autumn: March to May
March is essentially summer extended — warm, settled, often sunnier than February. April cools gently to highs of 20°C and lows of 12°C, and May brings the first real chill with highs of 17°C and lows of 9°C. Rainfall increases through autumn, particularly in May. Sea temperatures stay swimmable through March (20°C) but drop to 17°C by May.
What to do: hiking the Hunua Ranges and Waitākere tracks (cooler, less mosquitoes); winery tours of Waiheke and Matakana; Auckland Lantern Festival in March; Pasifika Festival; vineyard harvest events; long walks along the waterfront. Crowds are noticeably thinner than peak summer — book accommodation 2–4 weeks ahead, not 2–3 months.
What to pack: jeans and trousers, T-shirts and long-sleeved tops, a sweater or light jacket, comfortable walking shoes, a packable umbrella, a wind-resistant rain layer for May. You’ll still want sunscreen — UV is moderate but not negligible.
Winter: June to August
Auckland winters are mild compared to most of the world — highs of 14–16°C, lows of 7–9°C — but they’re damp. June, July and August deliver Auckland’s wettest weather, with July averaging 147 mm of rain across 14 rainy days. Daylight is short (sunset around 5:15pm in mid-June) and the wind off the Tasman can bite. Mountains in the central North Island do get snow, but Auckland itself doesn’t.
What to do: NZ International Comedy Festival (May–June); Matariki — the Māori New Year, public holiday in late June or early July with cultural events across the city; Restaurant Month deals; cosy whisky bars and cafes in Britomart and Ponsonby; ferry trips on Hauraki Gulf storm-watching days; ski day-trips down to Mount Ruapehu (3.5 hours’ drive). Crowds are at their thinnest, and accommodation rates are at their lowest.
What to pack: waterproof jacket (essential), warm sweater or fleece, jeans, closed-toe shoes (preferably waterproof), scarf, beanie, packable umbrella, layers. New Zealand homes are famously poorly insulated and often colder indoors than out — bring an extra layer for evenings.
Spring: September to November
Spring is volatile but rewards you for showing up. September is still cool — highs of 15°C — but by November the city has properly turned, with highs of 19°C, sea temperatures climbing back to 17°C, and gardens exploding into bloom. The pōhutukawa (New Zealand Christmas tree) flowers crimson from late November. Watch for “spring storms” in September and October — sharp wind events that can cancel ferries.
What to do: Auckland Diwali Festival (October); New Zealand Fashion Week; whale and dolphin tours (active spring season); Auckland Botanic Gardens and Cornwall Park spring bloom; the city’s parks come alive after winter. Crowds remain manageable through September and October but ramp up sharply in late November as Christmas holiday season approaches.
What to pack: layers, layers, layers — a T-shirt, a long-sleeve top, a sweater, a packable rain shell. Add a sunhat and sunscreen for late spring. Closed-toe shoes for windy harbour walks; sandals or trainers for warmer days.
Auckland weather month by month
January — peak summer
Average high 23°C, low 15°C, rainfall 75 mm across 10 days, sunshine 7–8 hours/day, sea 21°C. The first three weeks are New Zealand’s main holiday period — the city is half-empty as locals flee to the beach, but accommodation rates are at their highest and beach towns like Pauanui and Mt Maunganui are heaving. Auckland Anniversary Day (last Monday) brings the biggest sailing regatta in the Southern Hemisphere onto the Waitematā Harbour. ASB Classic women’s tennis runs early January, men’s tennis the second week. UV peaks at 12 (extreme) — sunscreen is non-negotiable.
February — warmest month
Average high 23.7°C, low 16.3°C, rainfall 75 mm, sunshine 7 hours/day, sea 22°C (warmest of year). Often considered Auckland’s best month — kids are back at school, crowds thin out, and the weather is at its most stable. Lantern Festival in mid-February draws 200,000+ visitors to Auckland Domain. Splore music festival (third weekend) is the country’s most acclaimed boutique festival. Humidity is high — pack moisture-wicking clothing.
March — Indian summer
Average high 22°C, low 14.7°C, rainfall 88 mm, sunshine 6.5 hours/day, sea 20°C. March often outperforms February for sun — settled weather and lower humidity make this many locals’ favourite month. Pasifika Festival celebrates Pacific Island cultures at Western Springs (mid-March). Wineries on Waiheke and in Matakana host harvest events. Sea remains swimmable, beaches uncrowded.
April — autumn arrives
Average high 19.7°C, low 12.6°C, rainfall 100 mm, sunshine 5.5 hours/day, sea 18°C. ANZAC Day on 25 April marks the start of the cool season — dawn services at the Auckland War Memorial Museum and around the city. Daylight saving ends on the first Sunday of April, so evenings get noticeably shorter. Easter falls in March or April — a four-day public holiday with major retail closures on Good Friday and Easter Sunday.
May — pre-winter
Average high 16.6°C, low 10.4°C, rainfall 113 mm, sunshine 4.5 hours/day, sea 17°C. The first cold snap of the year typically lands in early May. Auckland is mostly dry but rainfall jumps.

June — winter begins
Average high 14.7°C, low 8.5°C, rainfall 137 mm, sunshine 4 hours/day, sea 15°C. Shortest days of the year — sunset before 5:15pm at the solstice (around 21 June). Matariki public holiday falls in late June or early July depending on the lunar calendar — expect cultural events, light installations and Māori-led ceremonies. School holidays mid-July push families to ski fields. Auckland’s coldest mornings dip to 5°C in outer suburbs but rarely freeze in the CBD.
July — wettest, coolest
Average high 14.5°C, low 7.9°C, rainfall 147 mm, sunshine 4 hours/day, sea 14°C. The year’s wettest month and the coldest mornings, but daylight is already getting longer after the solstice. Auckland International Film Festival starts late July at the Civic Theatre and runs through August. School holidays give way to a quieter August. Best time for budget travel — flights and accommodation are at their lowest, particularly mid-week.
August — late winter
Average high 15°C, low 8.6°C, rainfall 132 mm, sunshine 4.5 hours/day, sea 14°C. Slightly drier than July, with longer days and the first hints of spring colour in late August. Auckland Restaurant Month delivers prix-fixe menus from $50 at the city’s best venues. Bell-bottoms of bird species (tūī, kererū) become noticeable in suburban gardens.
September — spring stirs
Average high 15.5°C, low 9.4°C, rainfall 99 mm, sunshine 5 hours/day, sea 14°C. Cherry blossoms appear in Auckland Botanic Gardens and Cornwall Park. Daylight saving begins on the last Sunday of September — clocks spring forward. Magnolia and rhododendron season. The first warm-weather bookings start arriving for summer — book ahead if you’re aiming for January–February visits.
October — proper spring
Average high 17°C, low 11°C, rainfall 102 mm, sunshine 5.5 hours/day, sea 15°C. School holidays mid-October bring families out. Diwali Festival of Lights at Aotea Square in late October. Auckland Marathon (last Sunday of October) brings 17,000+ runners across the Harbour Bridge. Whale watching is excellent — humpbacks pass through the Hauraki Gulf en route to Antarctic feeding grounds.
November — summer warm-up
Average high 19°C, low 12.6°C, rainfall 92 mm, sunshine 6.5 hours/day, sea 17°C. Pōhutukawa trees burst into red bloom from late November — Auckland’s signature Christmas image. NZ Fashion Week mid-November. Garden festivals; the Heroic Garden Festival opens private CBD gardens to the public. Sea temperatures still on the cool side for swimming but local kids are already in.
December — early summer
Average high 21°C, low 14°C, rainfall 92 mm, sunshine 7 hours/day, sea 19°C. Christmas in summer — a strange experience for first-time visitors. Schools and many businesses close from 22 December to mid-January. Boxing Day sales drive the year’s biggest retail crowds. Sky Tower fireworks light up the city on New Year’s Eve. Beaches busy on weekends; book popular restaurants and ferry tickets to Waiheke ahead.
When is the best time to visit Auckland?
The honest answer depends on what you want.
- For warmest weather and beach: February. Warmest sea, most stable weather, slightly thinner crowds than January.
- For best value: May–August. Accommodation can be 30–50% cheaper than peak summer.
- For sweet-spot weather without summer crowds: March or November. Mild days, smaller crowds, full price relief mid-shoulder.
- For festivals and events: January (regatta, ASB Classic), February (Lantern, Splore), March (Pasifika), October (Diwali), New Year’s Eve.
- For wine touring: March–April (post-harvest events) or October (vineyard re-openings, white wine releases).
- For hiking and outdoors: March–May or September–November. Cooler, fewer mosquitoes, drier than midsummer downpours.
- For Māori cultural events: Late June or early July (Matariki); Anniversary Day late January (Tāmaki Herenga Waka Festival).
For most international visitors with flexible dates, late February through April is the sweet spot — the weather is at its most reliable, the city is in full swing, and crowds are manageable. October and November offer similar weather and even smaller crowds, though the mid-November pōhutukawa bloom comes too late for spring planners.
Auckland weather quirks every visitor should know
“Four seasons in one day”
This isn’t a marketing slogan — it’s a daily reality. A 22°C sunny morning can flip to a 14°C wet afternoon as a southerly front sweeps through. Always carry a packable rain layer and a thin warm layer, regardless of the morning forecast. Watch the harbour: when whitecaps form on the Waitematā, the wind is about to shift.
UV is brutal
Don’t underestimate the New Zealand sun. The ozone hole over Antarctica thins protection over New Zealand, and the unpolluted air means more UV reaches the ground. Auckland’s UV index regularly hits 11–12 in summer (extreme — burn time under 10 minutes). The “slip, slop, slap, wrap” rule (slip on a shirt, slop on sunscreen, slap on a hat, wrap on sunglasses) is taught from kindergarten. Apply broad-spectrum SPF 50+ every two hours when outdoors, and reapply after swimming.
West coast vs east coast micro-climates
The city straddles two coasts with very different weather. The west coast (Piha, Karekare, Bethells, Muriwai) faces the Tasman Sea — wilder, windier, wetter, wave-pounded black-sand beaches. The east coast (Mission Bay, St Heliers, Takapuna, Cheltenham) faces the Hauraki Gulf — sheltered, sunnier, calmer, golden-sand swim beaches. If west-coast weather looks rough, east-coast beaches are usually fine. CBD weather is closer to east-coast conditions.
Wind chill matters
Auckland is one of the windiest cities in the world by some measures, especially in winter when westerlies and southerlies dominate. A 14°C day with 30 km/h wind feels like 10°C. Pack a wind-resistant outer layer rather than a heavy coat — you’ll be more comfortable.
Indoor temperatures lag outside
Older New Zealand homes (anything pre-2008) have famously poor insulation and minimal heating. Hostels, Airbnbs and motels are notoriously colder inside than out in winter. Modern hotels and serviced apartments are usually fine. If you’re staying in budget accommodation in winter, check that the listing has a heat pump or pack your warmest pyjamas.
Auckland weather and outdoor activities
Most visitor activities are weather-resilient if you plan around the conditions. Some are weather-dependent. Here’s how to think about it:
- Sky Tower SkyWalk and SkyJump: run rain or shine, but cancelled in high winds (above 30 km/h sustained). Check before you book.
- Waiheke ferries: 99% reliable; Fullers cancels in extreme southerlies — check the AT app for service status before heading to the ferry terminal.
- West-coast beach trips: avoid in heavy rain (slips on the access roads), strong westerlies (dangerous surf) or thunderstorms.
- Hiking the Waitākere Ranges and Hunua Falls: tracks open in light rain, close after major storms. Some tracks are kauri dieback closed indefinitely — check the Auckland Council website before you go.
- Sailing on the Waitematā: best in 10–20 knots from anywhere except the south. Lots of operators run year-round.
- Kelly Tarlton’s, Auckland Museum, Auckland Art Gallery, MOTAT, Stardome: excellent rainy-day options.
- Wineries: mostly indoor tastings — viable in any weather, plus open-air decks for fine days.

Auckland weather forecasts and apps
The most reliable Auckland forecasts come from MetService (the official New Zealand meteorological service) and NIWA. The MetService app is free, accurate, and pulls hourly forecasts. WeatherWatch.co.nz is a good independent alternative with strong commentary. Avoid relying on global apps like Apple Weather or Google for fine-grained accuracy — they often miss localised showers. RainViewer is excellent for tracking individual squalls in real-time radar.
For surf, swell and tide information: Surf2Surf, Surfline and the Coastguard NZ app. For UV index and burn-time predictions: NIWA’s UVI Atlas. For tramping and outdoor track conditions: the Department of Conservation app and Auckland Council’s regional parks pages.
Auckland weather FAQs
Does it snow in Auckland?
Effectively never. The last meaningful snow in central Auckland fell in 1939. Brief snow flurries occasionally reach outer southern suburbs in extreme cold snaps, but the city’s coastal sub-tropical climate keeps freezing temperatures rare. For real snow, head south to Mount Ruapehu (3.5 hours) in winter.
What’s the rainiest month in Auckland?
July, with an average of 147 mm of rainfall across 14 rainy days. June and August are also wet (130+ mm each). The driest months are January and February (around 75 mm each), though summer downpours when they happen can be intense.
Is the sea warm enough to swim in winter?
Not for most people. Sea temperatures bottom out at 14°C in August — uncomfortable without a wetsuit. May to October sees temperatures of 14–17°C. Comfortable swimming runs December to April (18–22°C). Local surfers wear 4/3mm or 5/4mm wetsuits in winter and 3/2mm in summer.
When is the cheapest time to visit Auckland?
May to early September. Hotels can be 30–50% cheaper than December–February peak. International flight prices follow a similar pattern, especially mid-week departures. The shoulder months of late April, October and November also offer significant savings without true winter weather.
When is the worst weather in Auckland?
July is statistically the wettest and coolest. June, July and August see the shortest days and the most southerly storms. That said, “worst” weather in Auckland still means highs of 14–15°C — far from extreme. Summer can produce its own challenges in the form of subtropical thunderstorms and ex-tropical cyclones (rare but disruptive), most likely January through March.
Are summers humid in Auckland?
Yes, moderately. Humidity averages 70–80% in January and February, with sticky overnight lows in the high teens. Air conditioning is increasingly common but isn’t universal — ask before booking accommodation in summer if humidity bothers you.
When does daylight saving start and end?
New Zealand Daylight Time runs from the last Sunday in September to the first Sunday in April. Clocks spring forward 1 hour at 2am on the start date, fall back 1 hour at 3am on the end date. Daylight saving extends summer evenings to 9:30pm at the solstice — perfect for outdoor dining.
Should I bring an umbrella or a raincoat?
Both, ideally. Auckland’s wind often makes umbrellas useless — the rain comes sideways. A breathable rain shell handles most weather. A small wind-resistant umbrella (the inverted, double-canopy type) is a useful backup for CBD wandering between cafés.
What’s the weather like for the Sky Tower views?
Best viewing days are stable, settled days with light westerly winds — common in February, March and November. Avoid heavy-shower days (visibility drops to 1–2 km). Sunset visits are spectacular year-round; clear winter mornings give the sharpest distance views to the Hauraki Gulf islands and Coromandel.
Does Auckland get cyclones?
Auckland sits at the southern edge of the South Pacific cyclone belt. True cyclones don’t reach the city, but ex-tropical cyclones — weakened tropical systems heading south — occasionally bring damaging wind and rain. The peak risk window is late January to early April. February 2023’s Cyclone Gabrielle brought severe damage to parts of Auckland, but events of that scale are rare. Standard travel insurance covers weather disruption.
Is Auckland warmer than Wellington?
Yes, consistently. Auckland averages 2–3°C warmer year-round, has fewer windy days (Wellington is the windiest capital in the world), and gets more sunshine hours. South Island cities (Christchurch, Queenstown) are colder again, with proper snowy winters.
The bottom line
Auckland’s weather is mild, ocean-influenced and changeable — and that’s exactly what makes it so liveable. There’s no bad time to visit, just different versions of the same generally agreeable climate. Layer up, pack a rain shell, slap on sunscreen, and you’ll be ready for whatever the day throws at you.
