GLADSTONE was unprepared by the sudden mercury drop over the weekend, as the region recorded its lowest temperatures since August last year.
The lowest temperatures were recorded Monday morning after the cold snap began on Saturday night.
Eight degrees was recorded at Gladstone airport but it was much worse inland, with Biloela reaching a minimum of 1.7 and Clermont dropping to zero.
With a fireplace at home, the chilly weather didn't bother 15-year-old Caitlin Bartlett.
"This one was a bit unexpected but you sort of get used to them," she said. "It is easier to keep warm than to stay cool."
Rockhampton Bureau of Meteorology observer Brendan Bradford said the worst was over for now, but more cold snaps would hit as winter approached.
"We are nowhere near records yet. Temperatures in Gladstone have been down to 4.9 degrees in May before," he said.
