GYMPIE was hit with the coldest August morning in five years today as the temperature swung sharply below zero, delivering a 'feels like' temperature of -1.7C as frost and fog blanketed the region.
The temperature officailly dropped to -0.3C at 6.20am; which is not only 7C degrees below the average for this time of year, but 15C colder than yesterday morning.
The combination of north-westerly winds and a warm atmosphere yesterday and Monday delivered much-higher than average minimum temperatures, before a south-westerly change moved in, Bureau of Meteorology forecaster Adam Blazak.
Mr Blazak said while a 15C fluctuation is fairly large, it is not uncommon to see two or three cool changes in each winter month.
Tomorrow morning is still expected to be "fairly fresh" the forecaster said, with an expected two degree increase in the minimum, but by the weekend moisture returning to the air will bring temperatures back to the average.
