In the latest episode of what's been a year of extreme weather, it appears summer is back.

Most of the country is in for a weekend of sunshine and scorching temperatures - but the good weather probably won't stick around.

MetService meteorologist Ravi Kandula said the forecast was fine for the North Island over the weekend, with sunshine expected for much of Friday and Saturday.

"We're expecting that accumulations will only be significant rain-wise in Fiordland and Westland for the next few days," Kandula said.

"Essentially, most of the country will be pretty good."

Temperatures would hover around the mid 20's for most of the Island, peaking in the high 20s.

The South Island could expect some cooler temperatures but the difference was "nothing too drastic", Kandula said.

The weather looked set to take a turn for the worse early next week, with showers becoming heavy and temperatures dropping to the low 20s.

A drop in temperatures would be more dramatic as you headed down the country, with temperatures dropping as low as 17C in spots like Wellington and Christchurch.

MetService said the impact Cyclone Gita would have on New Zealand was too far ahead to accurately forecast.
