Hastings will retain its high temperatures later into next week, with highs of 24C and 21C on Tuesday and Wednesday respectively.
Napier is expected to see highs of 24C and 21C, with overnight lows of 11C and 9C.
Rain will begin to develop in both districts on Wednesday according to McInnes, with a southerly change expected in the afternoon.
"A front comes up over the whole country on Wednesday, which will affect the North Island, specifically Hawke's Bay," he said.
"The low and mid-20s at the start of the week will start to drop on Wednesday, where it'll be more like highs and mid-teens."
Occasional patches of rain will continue into Thursday with south easterlies also expected.
