Due to its outback location, Alice Springs' overall climate is predictably dry and arid most of the time, without a real wet season. Rainfall varies from year to year, but if there has been a considerable amount of winter rain the wildflowers and plant life will spring up from August through October. Temperatures can get as high as 48°C (118°F) in summer and can drop as low as -7°C (19°F) in winter. The best time to visit is in April and thereabouts - you'll miss out on summer's extreme heat, and still be far enough away from the cold season.
