If you're heading out for the afternoon in Auckland, take a brolly - there are showers lurking.
New Zealand's biggest city has faced a day of drizzle and dreary clouds, with southwesterly winds annoying unsuspecting city-dwellers not dressed for the wind.
However, the city's average temperature currently sits at 14C- practically balmy compared to further down the country.
According to the MetService, while the temperature in Invercargill is 5.5C right now, it feels like 0C thanks to strong southwesterly winds.

In Dunedin the temperature is 6C but it feels like 3C, with possible snow flurries predicted down to 400m.
And in Christchurch and Ashburton overnight the temperature is expected to drop to -2C as the polar blast hits.
Oamaru and Wanaka can expect an overnight low of 0C while Timaru could plunge to -3C.
MetService said a series of fronts would bring unsettled weather from midweek, with "on again off again" rain mixed with sunshine, except in eastern areas which would be drier.
"Parents will be pleased that although there is some wet weather during the school holidays, the kids will get a chance to be active outside from time to time," MetService meteorologist Andrew James said.

"Thursday looks like the best day this week for most places."
Northwesterlies would also bring warmer than average temperatures, but unsettled conditions would continue into next week.
Weatherwatch said westerly winds would dominate for up to a fortnight - unusual for mid-winter.
"This more spring/autumn-like pattern means a variety of milder days and colder ones across the country with coldest air sticking to the south and warmest air sticking to the north," the forecaster said in a statement.
"The dominant westerly flow will also mean a build-up of rainfall on the West Coast while eastern regions stay dry to fairly dry."
For Auckland that means 10 days of rain, with the wet really setting in next week.
This weather pattern means frosts are less likely over the next two weeks, although due to a polar southerly in the South Island today some frosts will be occurring this week in the calm spells.
It's southwesterlies and a few showers today and tomorrow, but a front on Wednesday signals the beginning of an unsettled spell. Expect on again off again rain from mid-week, but not much will get to the east of either island. https://t.co/Yjbq0jxdqz ^AJ pic.twitter.com/DysuYQAHtQ
