Weather in New Zealand: Climate, Seasons, and Average Monthly Temperature

New Zealand enjoys a moderate climate, without extremes of hot or cold. This is due not only to the latitude of the country but to the fact that most of New Zealand's landmass is relatively close to the sea. Having such a maritime climate means there is an abundance of sunshine and pleasant temperatures for most of the year.

New Zealand's long narrow shape is dominated by two main geographic features—the proximity of the sea, and mountains (the most famous of the latter are the Southern Alps which traverse almost the entire length of the South Island). The North and South Islands have quite different geographic features and this is reflected in the climate as well. Both islands experience a marked difference in the weather between the eastern and western sides, too. The prevailing wind is westerly, so on that coast, the beaches are generally wild and rugged with stronger winds. The eastern coast is much milder, with sandy beaches good for swimming and generally fewer rainy days.

In the far north of the North Island, summer weather is subtropical and high in humidity with temperatures as warm as 86 degrees Fahrenheit (30 degrees Celsius). Winter temperatures are rarely much below freezing on this island, apart from the inland mountain regions in the middle of the island. In any season, the North Island can receive quite high rainfall, which accounts for the country's lush green environment. Northland and Coromandel have higher than average amounts of rain.

The Southern Alps neatly divide the east and west coasts. South of Christchurch, snow is common in the winter. Summers can be hot in areas of the South Island.

Rainfall in New Zealand is reasonably high, although more so in the west than in the east. Where there are mountains, such as along the South Island, weather is cool and sees more rain. That is why then west coast of the South Island is particularly wet; in fact, Fiordland, in the southwest of the South Island has amongst the highest rainfall of anywhere on earth.

Any time of year is a good time to visit New Zealand; it all depends on what you are wanting to do. Spring, summer, and fall are busier, but the quieter months of winter (June to August) can be a wonderful time for snow-based activities such as skiing and snowboarding and the South Island. 

And remember, everything in the southern hemisphere is the other way around: It gets colder the further south you go, and summer covers Christmas while winter is in the middle of the year. A barbecue on the beach on Christmas Day is a long-held kiwi tradition that confuses many a visitor from the northern hemisphere!

Sunshine in New Zealand

New Zealand has the highest incidence of skin cancer in the world. The sun can be rather harsh and burn times are short, especially in the summer. It is essential to apply a high-protection sunblock in the summer months, but have it on hand no matter when you visit so that you can be protected on sunny days.

New Zealand enjoys long sunshine hours in most places and at most times of the year. There is not a huge difference in daylight hours between the summer and winter, although it is more accentuated in the south. In the North Island, daylight hours are generally from around 6 a.m. to 9 p.m. in the summer and 7:30 a.m. to 6 p.m. in the winter. In the South Island add an hour to the summer at each end of the day and subtract one in the winter for a very rough guide.

Auckland's subtropical climate is characterized by warm, humid summers and cool, wet winters. The city is one of New Zealand's warmest and sunniest, with an average daily temperature of 75 degrees Fahrenheit (24 degrees Celsius) in February.

The city receives significant rainfall year-round, usually upwards of 50 inches, but snowfall is extremely rare.


Rotorua is situated on a lake on New Zealand's North Island. It experiences a warm, temperate climate with nearly 60 inches of rainfall annually. The average year-round temperature in Rotorua is 64 degrees Fahrenheit (12 degrees Celsius), but winter temperatures can fall as low as 38 F (3.5 C). July is Rotorua's coldest month, while February is the warmest. 


Wellington experiences a marine climate with temperatures rarely exceeding 77 degrees Fahrenheit (25 degrees Celsius) or dropping below 39 F (4 C). During the winter months, the city receives southerly blasts which can make it feel much colder than it actually is. June and July are the wettest months in Wellington, and the city receives 49 inches of rain per year. Unlike much of the rest of New Zealand, Wellington does occasionally receive snow.


Christchurch has a mostly warm, oceanic climate with a sea breeze from the northeast. Temperatures usually range from 73 to 52 degrees Fahrenheit (23 to 11 degrees Celsius). During the winter months, the city experiences frost and occasional snowfall isn't uncommon. Smog is a frequent occurrence in Christchurch, especially during the winter when vehicle exhaust and smoke get trapped above the city. 


Queenstown temperatures hove around 70 degrees Fahrenheit (21 degrees Celsius) during the summer months. Winters, however, are equally cold with single-digit temperatures and snowfall. Queenstown is much drier than other parts of New Zealand, receiving just 29 inches of rain annually.
