Breaking down our weather seasons

Our climate is variable in this part of the world and today we’re looking at a couple of the bigger populated areas of the country and breaking it down into bite size chunks.

NIWA have provided this information and given us the different weather elements for 2 different regions.

How does it stack up do you think and would you add or alter any of the content?.

Northland, Auckland, BOP

This is a sub-tropical climate zone, with warm humid summers and mild winters.
Typical summer daytime maximum air temperatures range from 22°C to 26°C, but seldom exceed 30°C.
Winter daytime maximum air temperatures range from 12°C to 17°C.
Annual sunshine hours average about 2000 in many areas. Tauranga is much sunnier with at least 2200 hours. SW winds prevail for much of the year. Sea breezes often occur on warm summer days. Winter usually has more rain and is the most unsettled time of year.
In summer and autumn, storms of tropical origin may bring high winds and heavy rainfall from the east or northeast.


The climate of this zone is greatly dependent on the lie of the massive Southern Alps to the west.
Summer temperatures are warm, with highest temperatures occurring when hot dry foehn northwesterlies blow over the Alps and plains.
Mean annual rainfall is low, and long dry spells can occur, especially in summer.
For much of the time summer temperatures are moderated by a cool northeasterly sea breeze. Typical summer daytime maximum air temperatures range from 18°C to 26°C, but may rise to more than 30°C. A temperature of 42°C has been recorded in Christchurch.
Winters are cold with frequent frost. Typical winter daytime maximum air temperatures range from 7°C to 14°C. Northeasterlies prevail about the coast for much of the year. Southwesterlies are more frequent during winter.

Hi I lived in Tauranga for three years and always thought they had a lot more sunshine hours there. I’d be interested to see a comparison in annual rainfall between Auckland and Tauranga too, I always felt that Tauranga had more sun but similar or even slightly more rain. When it rains there it is usually a lot heavier than in Auckland.

Rainfall 1971-2000: Auckland (Owairaka) 1240mm, Tauranga Aero 1214. However when updates to 2110 are done, Auckland should have decreased a little, with Tauranga increasing. Tauranga leads a typical Auckland area by 200-250 hours of sunshine per year.
