The dry season from May through September is characterised by warm, sunny days and crisp winter nights.

The wet season, from November to March, is characterised by hot temperatures and monsoonal rain. However the increased rainfall results in spectacular waterfalls with lush green landscapes that engulf much of the region, including the Katherine region and Nitmiluk National Park.
