New Zealand is a land of dramatic contrasts, boasting mild temperatures and an abundance of sunshine. Most major centres sit near the coast, ensuring a temperate and inviting climate in New Zealand year-round. While the far north enjoys subtropical summers (December-February), the inland alpine areas of the South Island can experience crisp winters (June-August) as low as -10°C. Read on to understand the average climate in New Zealand to help you plan your visit.

Understanding the New Zealand Climate by Month
When deciding when to visit, looking at the New Zealand climate by month helps you align your itinerary with your preferred activities.
The average New Zealand temperature decreases as you travel south. January and February are the warmest months, and July is the coldest month of the year. In summer, the average maximum temperature ranges between 20-30ºC (70-90°F) and in winter between 10-15ºC (50-60°F).
New Zealand weather can change unexpectedly – as they say, you can experience four seasons in one day! Be prepared for sudden changes in weather and temperature if you’re doing outdoor activities, and we recommend taking both a showerproof jacket and sunscreen with you.

This variability is exactly what keeps the landscapes so breathtakingly green and is just one of the many amazing facts about New Zealand that make it such a unique destination to explore.

Regional Variations: Auckland and Wellington
The Auckland climate is distinct from the conditions found further south. Auckland sits on a narrow isthmus where its weather is heavily maritime-influenced, resulting in warm, humid summers and mild winters. While the humidity can make a 25°C day feel much toastier than the thermometer suggests, it’s this temperate weather that earns the region its "Winterless North" nickname. For a deeper look at the local conditions, seasonal averages, and what to pack, explore our Auckland climate guide.
Further down the North Island, in Wellington, the climate is shaped by its position on the edge of the Cook Strait. Known for its refreshing breezes, Wellington enjoys a temperate maritime climate. While temperatures are generally stable, the wind can bring a sudden chill, reinforcing the need for layers. Whether you’re in the north or the south, the climate New Zealand provides ensures that the air is always fresh and the scenery is perpetually lush.
New Zealand Climate vs UK: What to Expect
Comparing the New Zealand climate vs the UK offers a helpful perspective. Both nations share a maritime influence, which means neither typically experiences the extreme continental heat or cold of Europe or North America. Generally, New Zealand is sunnier and less prone to the long, grey spells often associated with British winters.
The most significant difference is the intensity of the sun; due to the exceptionally clear air and lower levels of ozone, the UV rays in the Southern Hemisphere are remarkably strong. Even on a cool or overcast day, you can burn much faster than in the UK. A high-factor sunscreen, a sun hat, and quality sunglasses are essential companions for any New Zealand journey.
