Although Darwin has a largely tropical climate, the Dry Season – roughly the end of April to October – can be pretty dry with low humidity. Prior to the Wet Season is a one or two month period known as the Build Up when the heat and humidity rises and large, dramatic thunderstorms move through without dropping any rain. In order to minimize the risk of brush fires from lighting strikes during this period, there are a lot of small, low-intensity prescribed burns to reduce the brush load. The aboriginal people used to follow a similar practice. Most of the shrubs in the background that look dead should revive, just like this one here, once the rains arrive.
