Unfortunately the last week of 2017 is not expected to be a typical Hawke's Bay summer one - a front moving up the country, dampening much of the South Island for Christmas, would reach Hawke's Bay on December 27 and bring cooler conditions.
Rain is expected from Wednesday onwards, with temperatures sitting at the relatively low high of 20C.
"How long it takes the rain to clear is a bit of a question mark," Mr Adams said. "But it should have improved by Friday."
However, this rain it is not all doom and gloom - the region's parched landscape is showing signs of unusually low levels of rainfall in November - with monthly averages below normal in most parts of Hawke's Bay.
"If the low pressure sticks around and Hawke's Bay gets rain for more than a day, it will make a difference [to dry conditions]," Mr Adams said.
Recent rain has been credited with allowing Hawke's Bay Fire Services a "reasonably quiet" week for vegetation fires - although they are reminding people to stay vigilant.
Both Napier and Hastings Fire Services said their biggest callout this week had been for a Wairoa vegetation fire which closed roads and took hours to get under control.
Emergency services were called to the bush fire near Waikokopu about 9pm on Wednesday. The fire forced the closure of the main road into Mahia, with crews from Mahia, Nuhaka, Napier, and Hastings called to fight the flames.
Crews had to stop overnight, but returned in the morning and were able to get the fire contained.
Hastings Fire senior station officer Mike Peachie said rain this month had "definitely" helped in reducing the number of callouts.
He reminded people to keep up with what restrictions were in place, and be sensible when lighting any type of fires - including barbecues.
"At this time of year, moving into the next three months it's better just not to light fires at all."
