Warmer weather is expected for most of the country today, but don't give up on your scarves just yet - strong winds may still carry a cold sting.

The MetService expected temperatures to pick up this week and WeatherWatch said a chilly spell should give way to warmer conditions.

"We're finally looking at the end of an extended cold spell of weather around the country, as a northeasterly airflow is set to take over and dominate conditions on Tuesday," WeatherWatch analysts Aaron Wilkinson and Drew Chappell said.

The northeasterly should contain a fair amount of windy weather, the WeatherWatch forecasters said, but a front would move into the west of New Zealand during the afternoon and evening.

"There could be some heavy rain with this front, with some parts of the West Coast of the South Island looking at heavy rain in the late afternoon and into evening."

WeatherWatch said Nelson, the Marlborough Sounds and some western parts of the North Island could also expect some heavy rainfall overnight.

The warmest place this morning is Whangarei at 12C, while the coldest is Timaru at -6.5C, the MetService said.

The wettest place is Hokitika, with 0.2mm of rain, and Westport is the windiest this morning with gusts of 24km/h.

The MetService said Auckland should have cloudy periods and the odd shower today, with a strengthening northeasterly and a high of 15C.
