TEMPERATURES on the Coffs Coast were so high yesterday, even air-conditioning systems had trouble keeping their cool.
The thermometer at the Coffs Harbour Meteorological Office hit 41.1 degrees at 1.34pm, just short of the December record of 42.5 set in 1981.
The sizzler came after an unseasonably warm night, when the temperature rose above 31 degrees about 2am.
While many people were looking for a cool way to spend the day, air-conditioning service crews were kept busy keeping cooling systems operational.
Ken Ferne, operations manager at Faircloth and Reynolds, said callouts for repair crews had doubled yesterday.
"Systems are just not coping because they are not made to operate in ambient temperatures like we have had today," he said.
Mr Ferne said the hot weather had also led to a rise in the number of inquiries for new air-conditioning systems.
Rural Fire Service crews were fighting a small blaze in the Nana Glen area yesterday afternoon, one of many small fires they had to deal with.
A cool change with possible showers was expected to arrive early this morning, with a maximum temperature of 24 degrees predicted for today.
Tomorrow's maximum is expected to be 23 degrees.
