Tuli Wilderness is a good destination year-round. Generally hot (daytime min 15°C max 40°C) from October to March, and cooler from April to September (daytime min 10°C max 30°C). Birding is particularly good between October and March, depending on when the rains arrive. At this time the bush is also particularly lush with wildflowers blooming. The bush thins out from March onwards and is at its driest from July to October.
