New Zealand's seasons are the opposite of the Northern Hemisphere. Summer is December to February, winter is June to August. The country stretches 1,600 km from subtropical Northland to near-Antarctic Southland, so weather varies hugely depending on where you are. The famous saying "four seasons in one day" is genuinely true — especially in Wellington and on the South Island's West Coast.
Summer (Dec–Feb): 20–30°C in the north, 15–25°C in the south. Long daylight hours (up to 9:30pm sunset).
Autumn (Mar–May): 15–22°C. Stable weather, fewer crowds, stunning colours. The sweet spot for many travellers.
Winter (Jun–Aug): 8–15°C in the north, 2–10°C in the south. Snow on the mountains. Ski season. Shorter days.
Spring (Sep–Nov): 12–20°C. Lambing season, gardens blooming, shoulder-season prices. Weather can be unpredictable.
Month by Month
December – February (Summer / Peak Season)
The best weather, the longest days, and the highest prices. This is when everything is open, every tour is running, and every campsite is full. If you want guaranteed warm weather for beaches, hiking and road trips, this is the time. But you'll pay premium prices for accommodation and flights, and popular spots like Queenstown, Abel Tasman and the Great Walks will be busy. Book everything months ahead.
March – April (Autumn / Shoulder Season)
Our pick for the best overall time to visit. The summer crowds have thinned, prices drop 20–40%, the weather is still warm and settled, and the autumn colours in Central Otago (Wanaka, Arrowtown) are spectacular. March water temperatures are the warmest of the year. Most activities are still running. The only downside is shorter daylight hours compared to December–January.
May (Late Autumn)
Shoulder season pricing, cooler temperatures, and the start of snow on the mountains. Some seasonal activities begin to close (Glacier Explorers at Mt Cook shuts late May). Good for travellers who prefer fewer crowds and don't mind layering up.
June – August (Winter)
Cold but beautiful. Ski season at Queenstown (Coronet Peak, The Remarkables), Wanaka (Treble Cone, Cardrona) and Mt Ruapehu near Taupō. Hot pools and geothermal are arguably better in winter (Rotorua, Hanmer Springs). Accommodation is cheapest. The downside: shorter days, some roads can close in snow, and many tour operators in smaller destinations have reduced schedules or close entirely.
September – November (Spring / Shoulder Season)
Spring flowers, lambing, and everything waking up. Prices are still shoulder-season. Weather is highly variable — you can get all four seasons in a day easily. September and October can be wet, especially on the West Coast. By November, conditions improve significantly and it's a great time to beat the Christmas rush while still getting good weather.
Best Time For...
Hiking / Great Walks: Late November to early April. Great Walk huts are only serviced October to April. The Abel Tasman Coast Track and Tongariro Alpine Crossing are best December–March.
Skiing: Mid-June to early October at most fields. July–August is peak snow. Queenstown, Wanaka and Mt Ruapehu are the main ski areas.
Road trips: December to March for the most reliable weather, but March–April gives you the same great driving with fewer campervans on the road. See our road trip guide and campervan guide.
Whale watching (Kaikōura): Year-round. Sperm whales are resident. Humpbacks June–July. Orcas December–March.
Budget travel: May–September. Accommodation 30–50% cheaper. Flights cheaper. Fewer tourists. You trade weather for savings.
Beaches & swimming: December to March. Water temperature peaks in February–March. Coromandel, Abel Tasman and Northland have the warmest water.
Regional Differences
Northland & Auckland: Subtropical. Warmest region. Rarely below 10°C even in winter. Summer humidity. Can rain any time of year.
Central North Island (Rotorua, Taupō): Inland climate. Warm summers, cold winters. Frost common in winter. Geothermal areas steam more dramatically in cold weather.
Wellington: Notoriously windy. The "Windy Wellington" reputation is earned. Four seasons in one day is standard. Bring layers regardless of season.
Canterbury & Mackenzie (Christchurch, Mt Cook): Dry east coast. Hot nor'west winds in summer can push temperatures above 35°C in Christchurch. Frosty winters. Mt Cook has its own microclimate and can be cloudy when the rest of Canterbury is sunny.
West Coast (Hokitika, Fox Glacier, Milford Sound): The wet side. Annual rainfall 3–5 metres in Milford Sound. Pack rain gear. The upside: waterfalls are more spectacular after rain, and the lush rainforest needs the moisture.
Queenstown & Central Otago: Continental climate — hot dry summers, cold dry winters. Snow on the surrounding mountains June–September. Beautiful autumn colours March–April.
