However, as the low moves away, the weekend and early next week were looking to be fine, warm and sunny.
Rotorua should expect 26C and 27C days on both Monday and Tuesday next week, close to 5C above average for January.
Tauranga was getting steamy from Sunday through to Tuesday with sunny 26C days, both temperatures considerably high than average.
While Whakatāne was set to take on 27C temperatures for both Sunday and Monday.
Best said January temperatures across the Bay of Plenty so far had been warmer than average.
This week's low temperatures had local fire authorities warning people that the fire risk was still high regardless.
Pumicelands deputy principal rural fire officer Steve Webb told NZME that the fire risk in the Bay of Plenty was higher than in the Napier area, where a forest fire razed 300 hectares of land last week.
The heightened risk comes as the Western Bay of Plenty District Council urged residents to conserve water.
Webb said the dry conditions were not uncommon for summer, but the drop in temperatures this year could mislead people to think the fire risk had, too.
"It just takes one person to make a mistake."
According to the NIWA New Zealand Drought Index map, the Bay of Plenty region was not experiencing anything near-drought conditions at this stage.
