Winters are mild and pleasant, moderated by southeasterly trade winds and far from cold. July is the coldest month of winter, with average daily temperatures still reaching 77°F (25°C). The summer months are warm and December is the hottest month, with daytime temperatures soaring to 88°F (31°C). Townsville is prone to tropical cyclones between November and May which form mainly over the Coral Sea.
