The climate in Melbourne is temperate, with a warm summer and moderate rainfall. Seasons are the reverse of those in the Northern Hemisphere, and they usually start very late: The "official" first day of summer is 21 December, but it doesn't feel like summer until mid-January or later.
Spring is cool and extremely variable—often windy and rainy. Summer is warm to hot, with temperatures sometimes topping 100 F/40 C in late January and February. Autumn is usually balmy and mild, and it can last well into June. Winter—not the best time to visit—varies from mild to cold and rainy. Average temperatures range about 82 F/28 C in January to 68 F/20 C in April and October to 57 F/14 C in July.
