Your complete Christmas Day weather forecast

Mother Nature has a great Christmas gift for most holidaymakers in New Zealand tomorrow, with most regions likely to receive sunshine.

Cantabrians have clearly been good this year, with temperatures forecast to reach near 30C in the region.

Southlanders seem to have been the naughtiest this year with a high of only about 18C expected - not that that's particularly cold for them, said a MetService spokesman.

"Te Anau, the maximum there is 18 degrees, Gore 18 degrees as well - which makes sense because a front will move through them during the morning," he said.

"It's got relatively cool air behind it - it's a cold front, but it's not catastrophic, it's pretty good for down there."

He said a trough could bring rain to parts of the western North Island, although most parts of the island should be fine.

"Auckland should be pretty good for most of the day, with long fine spells and a few showers at night.

"Wellington should miss most of the wet weather with a few showers and some clouds," he said.

Southland, West Coast, and Otago will likely see rain early on as the front moves up the country with rain developing late for Canterbury and Marlborough.

Today, hundreds of people avoided the Christmas rush at supermarkets and malls to bask in the sun at Mission Bay.

Trevor Whitmore was one such beach-goer who got out of the house with the family to enjoy the sun after a cold winter.

"The sun was out - beautiful day to take the kids down to enjoy the beach.

"They're loving it, you can see them throwing the frisbee around, so yeah, nah, they're going to enjoy a great Christmas Eve down here at Mission Bay," Whitmore said.
