Month-by-month weather across New Zealand's main regions -- so you can plan your visit with confidence.
Understanding New Zealand's climate
New Zealand spans 1,600 kilometres from north to south, meaning its climate varies enormously. The subtropical Far North has warm, humid summers and mild winters. The Southern Alps receive heavy snowfall and are home to active ski fields. Fiordland -- the wettest inhabited region on earth -- gets up to 8 metres of rain per year. Marlborough, just over the mountains, is one of NZ's sunniest wine regions.
As a general guide: New Zealand's seasons are the reverse of the Northern Hemisphere. December-February is summer (school holidays, peak season, highest prices). June-August is winter (ski season, smaller crowds, lower prices outside ski resorts).
About Milford Sound and Fiordland: Rain here is not a reason to delay or cancel your visit. The waterfalls multiply, the mist sits dramatically in the valley walls, and many guests say the rainy-day experience is more extraordinary than a clear day. Plan for it, embrace it.

Packing for NZ weather: the golden rule
New Zealand's weather is famously changeable -- there is a local saying: "if you don't like the weather, wait five minutes." This is especially true in the South Island and at altitude. The advice from every experienced NZ guide:
Layer, don't bulk. A base layer, mid-layer fleece, and a waterproof outer shell handles nearly every situation
A compact waterproof jacket is non-negotiable regardless of season -- even in summer, a shower can arrive quickly
Sun protection is serious. New Zealand has a hole in the ozone layer overhead -- UV levels are significantly higher than in Europe or northern Asia at the same air temperature. SPF 50+ sunscreen and sunglasses are essential even on overcast days
