Cooler temperatures are expected this week as wintry air arrives in the region, MetService says.

MetService forecaster Frances Russell said clear skies were expected today, with northwesterlies developing.

Tomorrow would start fine with showers spreading from the west in the evening and westerlies dying out, she said.

On Wednesday showers would develop, persisting through Thursday, and dying out on Friday.


A downward trend in temperatures was expected from today onwards.

Napier would enjoy a daytime high of 20C today and that was expected to be the highest temperature this week. The daytime high would lower to 18C tomorrow, and 16C on Wednesday.

The colder weather forecast for this week comes after above-average temperatures were recorded in the region last month.

Niwa forecaster Chris Brandolino said Hawke's Bay had a mean daytime temperature of 20.6C last month, 1.3C above the 30-year average.

"Anything above 1.2C is considered well above average," Mr Brandolino said.

Hawke's Bay's highest daytime temperature last month was 24.9C, recorded at Napier Airport.
