New Zealand weather overview

Given its South Pacific location (1,200 miles (1,900km) from the nearest landmass), New Zealand has a sunnier climate than one might expect. Its North and South Islands are hilly and mountainous with excellent winter sports in the Southern Alps and spectacular fjords and glaciers. Auckland lies at the top of North Island, the warmest part of New Zealand, and its inhabitants bask in subtropical conditions and enjoy mild winters and warm, humid summers although they can be rained on at any time of the year.

On the southern coast, where Wellington and Napier are located, temperatures are slightly lower than in the north and inland conditions can become very frosty during the winter.

South Island, which houses Christchurch and Dunedin, is rather colder than North Island and has more of a maritime climate with little variation in coastal temperatures between summer (October to March) and winter (April to September). Inland, winters are colder with occasional snow on lower ground and heavy snowfalls in the mountains.

Rainfall is high on the west coast throughout the year but the Canterbury Plains are the driest part of New Zealand.

What to pack for New Zealand weather

Take light clothing if you are travelling in the summer or confining your visit to North Island. On South Island, fairly warm clothes are needed for the winter with heavier wear for trips to the mountains. Whenever you go and wherever you are going, anticipate some rain!
