What Are the Warmest Cities in New Zealand?

New Zealand’s climate is relatively mild year round, both in the warmest as well as the coldest parts of the country. But there are some cities that have an even better climate. If you’re a fan of warm temperatures, this article is for you.

I’m going to share with you my list of the warmest New Zealand cities with at least 5,000 residents. I’ll cover the top 10 in more detail and then present the entire ranking in a table with 40 major cities in the country.

Top 10 Warmest Cities in New Zealand

Here are the top 10 warmest places in New Zealand. They’re ranked by their annual daily mean temperature. Each city also includes temperatures in January and July to give an example of average summer and winter temperatures.

South Island is not represented in the top 10 because it’s much colder than the North Island. Dunedin is the warmest city on the South Island and it would place #19 in this ranking.

It gets 2,346 sunshine hours a year, compared to about 2,250 in other sunniest cities. New Zealand is one of the best countries for outdoor enthusiasts and Tauranga is one of the best choices in the country for an active lifestyle with favorable weather conditions.

7. Napier – 14.75 °C

The coastal city of Napier and the neighboring inland city of Hastings in the Hawke’s Bay region are two of the driest cities on the North Island. They owe their favorable climate to the rain shadow effect of the North Island Volcanic Plateau and surrounding mountain ranges such as the Kaweka Range that block the precipitation. Because of the combination of some of the warmest and some of the sunniest climates, Napier and Hastings offer the best weather in New Zealand for those who prefer sunny, warm days as often as possible.

Average high temperature in July: 14.1 °C

Average high temperature in January: 24.5 °C

8. Whakatāne – 14.5 °C

Whakatāne is a town in the Bay of Plenty region. It’s located about 87 km southeast of Tauranga. The town often records the highest annual sunshine hours in the country. In some years, it reached up to 2,600 sunshine hours a year, though the average is 2,251 hours, less than in Tauranga.

10. Hastings – 14.4 °C

Hastings, located 16 miles southwest of Napier, experiences the highest temperatures in the warmest months out of all cities in New Zealand. Because it’s not located on the coast, its high temperatures aren’t as moderated. As also one of the sunniest cities in the country, it’s one of the best places for people looking for the warmest weather possible.

Average high temperature in July: 13.9 °C

Average high temperature in January: 25.5 °C
