Rainfall is sparse and erratic, though variability is significantly less extreme than over the coastal Pilbara – the tenth percentile being vis-à-vis only in Onslow. It falls largely between December and March, with occasional rain events from autumn northwest cloudbands up to June. As little as can fall in a year; however, during heavy wet seasons when the monsoon reaches well south into the Pilbara, the rainfall can be significantly more – as much as fell between April 1999 and March 2000, and fell in 1980 owing to several tropical cyclones. The most rain recorded in a month is in March 2007, and the most in one day on 2 March 1941.
