Last night was expected to be the coldest night of the week, with a chance of frost in some areas, according to MetService meteorologist Claire Flynn.
Tomorrow and Wednesday evenings would have brief periods of rain and showers but the rest of the week should be mostly fine, she said.
Today was looking fairly fine thanks to wind from the north-west, which rarely brings rain to Hawke's Bay.
Tomorrow will have a high of 20C and the evening could see a period of rain as a trough travels across the region.
On Wednesday north-westerlies strengthen, which could bring high cloud and a few spots of rain but not much.
