When to Go
Adelaide has the least rainfall of all Australian capital cities, and the midday summer heat is oppressive. The Outback in particular is too hot for comfortable touring during this time, but Outback winters are pleasantly warm. South Australia's national parks are open year-round. The best times to visit are in spring and autumn. In summer extreme fire danger may close walking tracks, and in winter heavy rain can make some roads impassable. Boating on the Murray River and Lake Alexandrina is best from October to March, when the long evenings are bathed in soft light. The ocean is warmest from December to March.
