Lasting from May to October the low humidity is in contrast to the 'wet' season's tropical rainfall during November to April.
The Fraser Coast on the other hand features a subtropical climate meaning that although the weather is pleasant year round, the seasonal changes and temperature variations are more distinct. During December to February, summer temperatures fall between 23-32 °C while Autumn sees March to May hitting 18-28 °C. Winter cools to 13-26 °C during June to August and Spring is just a little warmer at 17-28 °C from September to November.
Following Queensland's coast south all the way down to Brisbane, the subtropical climate tends to mellow and the warm sunny weather remains mild and fairly consistent all year. The fine days give way to balmy nights with temperatures averaging 21-29 °C during summer and 10-22 °C in winter.
