However, the mainly fine week will get a few showers possibly in the middle of the week and towards the weekend, but compared to the rest of Aotearoa they are "blips in the radar".
With the showers on Wednesday, the northwesterlies will change to westerly, but shouldn't be notably strong.
Over the weekend the country as a whole was quite muggy and warm, and Hawke's Bay has been no exception with Wairoa being the second hottest part of the country on Sunday at 27.3 degrees Celsius and Hastings the fifth hottest at 26.4C.
But these temperatures won't be lasting long.
The air coming from the north of New Zealand which has been causing this is now disappearing and, with the westerly wind, temperatures will be "bang on average" for this time of year in the low 20s for much of the week.
Overnight temperatures are also sitting at the average of about 10C.
Tuesday is forecast to be 27C in Hastings, 26C in Napier, 24C in Waipukurau and 25C in Wairoa.
Wednesday and Thursday will be in the low 20s throughout the region.
Friday may also be a little hotter, brought on by some gustier northwesterlies, McInnes said.
Hastings and Napier are currently forecast to reach 25C, Waipukurau 22C and Wairoa 24C.
