Regardless of the parts of the country that you hope to explore, Australia is idyllic for a holiday during specific times of the year. Unlike Europe or even the Americas, the four seasons take place during different months of the year with summer weather lasting from December to February when it is wintertime in most of the world. As a rule of thumb, the spring and fall seasons are perfect for a trip as the weather is both pleasant and sunny. The months from March to May are considered the autumn period in Australia and temperatures fluctuate between 17 degrees Celsius and 35 degrees Celsius. The spring season, in contrast, lasts from September to November while the temperatures are identical to that of autumn. Avoid visiting Australia during the sweltering summer months and the cold winters as most outdoor experiences will be off limits or highly uncomfortable.
