Christmas day weather revealed: Here's what you can expect for the big day

Thunderstorms, sunshine, showers and warm temperatures are all on the Christmas Day weather menu, according to NIWA.

It's a mixed bag for the main holiday hotspots across the country for Christmas Eve through to Boxing day. 

NIWA meteorologist Seth Carrier said there's a chance of scattered afternoon showers and even thunderstorms across much of New Zealand throughout the holiday period.

"While temperatures on Christmas Eve may be slightly cooler than average, by Boxing Day most areas of the country will be enjoying warm weather, but it won’t be nearly as hot as the record or near-record temperatures last Christmas," Carrier said.

So here's what you can expect for the Christmas period.

Extended outlook

Low pressure located north of New Zealand may move south and bring rain and gusty easterly winds to the upper North Island in the 28-29 December time frame, while other regions generally enjoy quieter conditions with warm temperatures. However, a front moving north across the country will bring some showers and cool temperatures to eastern parts of New Zealand for the last couple of days of 2022.
