New Zealand is famous for its stunning landscapes, but the weather can vary a lot. It’s best to plan your trip based on when the weather is right for what you want to do. Here’s a quick guide to New Zealand’s climate, seasons, and month-by-month weather breakdown.
New Zealand’s Climate and Seasons
New Zealand has a temperate climate. However, since it’s in the Southern Hemisphere, the seasons are the opposite of those in the Northern Hemisphere.
You can expect warm summers that stretch from December to February. Winters run from June to August and vary depending on where you are. The northern parts are mild while the south gets colder, especially in the mountains where there is snow.
Spring (September to November) brings blooming flowers and mild temperatures, while autumn (March to May) usually has cooler temperatures with fewer tourists.
New Zealand’s weather is also quite unpredictable. It’s possible to experience all four seasons in one day, particularly in coastal areas. It pays to be ready for anything when you go.
Best Time to Visit New Zealand
If you’re into hiking, summer (December to February) is your best bet. The weather is mostly warm and dry, and the longer days give you more daylight for outdoor activities.

If you want to ski or snowboard, head over in winter (June to August). The southern Alps receive great snow, and the ski fields around Queenstown and Wanaka are perfect for winter sports enthusiasts.
Spring (September to November) and autumn (March to May) are great shoulder seasons. There’s less tourism, and the weather is still mild enough to enjoy hiking, biking, and sightseeing.
Packing Tips for New Zealand’s Weather
No matter when you visit, pack layers! The weather changes fast, and temperatures can drop even in summer—especially in the evenings. Bring a light jacket or sweater, plus a good pair of waterproof hiking shoes if you plan to explore the outdoors.
If you’re visiting in summer, sunscreen is a must! New Zealand has a high UV index, and you can get sunburned easily.
New Zealand’s Weather in January
January is right in the middle of summer. It’s one of the warmest months, with average highs around 25°C (77°F), especially in the north and central areas. Expect long days with lots of sunshine, making it ideal for beach trips and outdoor activities like hiking and swimming.
The South Island can be a little cooler than the North Island, and there’s always the possibility of some rain, so it’s smart to pack light layers and a rain jacket.

New Zealand’s Weather in February
February is still part of the summer season, but it starts to cool down slightly by the end of the month. It’s usually warm and dry, especially on the North Island. This is a great time for hiking, camping, and swimming. Beach towns are lively around this time.
As always in New Zealand, the weather can change quickly, so pack light clothing and something to keep you warm in the evenings.
New Zealand’s Weather in March
March marks the start of autumn in New Zealand. Temperatures are still mild, especially at the beginning of the month, with highs around 22°C (72°F). This is a great time to visit because the summer crowds have left, and accommodation prices start to drop.
It’s a good idea to bring a couple more layers or a sweater, as mornings and evenings start to get cooler.

New Zealand’s Weather in April
April is well into autumn, with temperatures continuing to drop. Daytime highs reach around 18°C (64°F), and it can get much colder in some areas, especially in the South Island.
The weather is cooler, but still quite pleasant for hiking or wine-tasting in regions like Marlborough or Hawke’s Bay. The leaves start changing color, making it a fantastic time to enjoy the autumn scenery.
New Zealand’s Weather in May
May typically brings cooler and wetter weather. Daytime highs sit around 15°C (59°F) and nights can feel chilly, particularly in the south. But on the plus side, it’s a quieter month for tourists, making it easier to explore fewer crowds.

If you’re visiting at this time, pack warmer clothes with lots of layers. A waterproof jacket is always useful.
New Zealand’s Weather in June
June marks the start of winter in New Zealand. Temperatures drop significantly, with average highs around 12°C (54°F), and snow falling in the mountains. It’s the perfect time to hit up New Zealand’s ski fields in the South Island, especially places like Queenstown and Wanaka.
If you’re traveling in the cities, winter would mean cooler days but nothing unbearable. Just be sure to pack warm layers and a coat.
New Zealand’s Weather in July
July is the heart of winter, and it’s also one of the coldest months. The North Island stays relatively mild, but the South Island, particularly in the alpine regions, sees freezing temperatures and snowfall.
This is another great month for winter sports, especially skiing and snowboarding. Ensure you’ve packed thermal layers and a windproof outer layer to keep warm.
New Zealand’s Weather in August
August is still winter, but by the end of the month, the country starts warming up slightly as spring approaches. Expect similar weather to July: cold but manageable in most areas, with snow in the mountains.
If you’re not into winter sports, cities and towns tend to be quieter now, so traveling around is peaceful. However, pack warmly, especially if you’ll be in the south.
New Zealand’s Weather in September
September is early spring. Temperatures start to rise and the snow begins to melt. It’s a wet month, though, especially in the central North Island and western South Island. Daytime highs reach about 15°C (59°F), but mornings and evenings can still be cold.
If you’re headed for hiking tracks, spring buds and greenery start popping up everywhere, making this a beautiful month. Bring layers because the weather can be very changeable.
New Zealand’s Weather in October
October is true spring. With temperatures around 18°C (64°F), it’s a great time to explore outdoors without big crowds. Spring flowers are in full bloom, and the country has a nice mix of clear skies and occasional rain.
The South Island can still be cooler, especially at night, so pack accordingly. Days are generally pleasant, and you’ll want to bring clothes you can layer.
New Zealand’s Weather in November
November brings early summer temperatures, hitting around 20°C (68°F). You can expect more consistent sunny days, though rain is always possible.
This is one of the best months for hiking and exploring the national parks. Days are longer, and the vegetation is lush and green. Make sure you’ve got a hat and sunscreen.
New Zealand’s Weather in December
December is the start of summer. Temperatures rise to around 22-25°C (72-77°F) as the days get longer and the sun stays out longer. Beaches and outdoor attractions get busier, but there’s still plenty of space to explore.
Even though it’s summer, always expect some rain or cooler evenings. Pack light layers, sunscreen, and a swimsuit.
Final Travel Tips for New Zealand’s Weather Year-Round
Regardless of the season, New Zealand’s weather is unpredictable. Always pack for layering so that you can stay comfortable, no matter what weather comes your way.
Make sure you bring waterproof gear and a good pair of walking shoes if you want to explore the great outdoors. If you’re renting a car, be aware there can be ice on the roads in winter or early spring, so drive carefully.
Plan based on what matters most to you: hot weather, winter sports, avoiding crowds, or seeing the blossoms in spring. New Zealand really has something for everyone at any time of the year!
