The changeable winds around New Zealand this week means some wildly swinging daytime temperatures – a classic spring set up especially in our nation’s east. Some areas will lift and drop by 8 to 10 degrees from day to day to day.
Eastern regions are more affected by the warm nor’westers with some days this coming week creating highs in the mid to late 20s, while other days it will be well down in the mid to late teens.
For example today, Sunday, the eastern side of the nation is warm with temperatures in both islands climbing into the low to mid 20s today. We can’t rule out some areas pushing closer to 30 degrees inland if the nor’westers peak with daytime sun.
But a cold front is coming overnight – so Monday will be a slightly cooler day with a southerly change for many regions.
Tuesday is a calmer day with lighter winds and higher air pressure.
By Wednesday west to north west winds return and temperatures start to climb back up again as rain clouds also push in to some areas.
Examples of daytime Highs in the east, west, north & south of each island this week:
Napier: Sun 26, Mon 18, Tue 24, Wed 23, Thur 26, Fri 26
Christchurch: Sun 23, Mon 18, Tue 21, Wed 24, Thur 15, Fri 17
Western areas aren’t so changeable with the bulk of the air coming off the Tasman Sea area:
Hamilton: Sun 22, Mon 17, Tue 18, Wed 21, Thur 20, Fri 20
Greymouth: Highs 16 or 17 daily.
Whangarei: Sun 22, Mon 18, Tue 18, Wed 22, Thur 23, Fri 21
Nelson: Sun 18, Mon 19, Tue 23, Wed 23, Thur 19, Fri 17
Wellington: Sun 18, Mon 16, Tue 18, Wed 18, Thur 16, Fri 17
Invercargill: Sun 15, Mon 17, Tue 17, Wed 15, Thu 14, Fri 13
As you can see eastern areas have the biggest highs, but also the biggest drops. Western and northern areas are most consistent while the coolest air definitely swipes the south of both the North and South Islands this coming week.
