Hot days in March: On average, Perth can expect about nine days when the maximum temperature is 32 degrees or higher. The greatest number of such hot days in March was 17 in 1983.

Days 40 degrees or higher in March: Daily maximum temperatures 40 degrees or above occur in Perth in about six years out of ten. The most recent event was 23 March 2005 when Perth experienced 41.9 degrees.

Note: Official Perth observations have been recorded at several different sites with varying instrumentation over the years, and these changes can affect the continuity of the climate record. For the current Perth (Mount Lawley) site, the most significant changes of this kind relate to temperature and rain days. For that reason, current mean temperature and rain-day data quoted here are based only on readings from the Perth (Mount Lawley) site, which commenced observations in 1993. Sunshine recordings are from Perth Airport and for similar reasons current means use only Perth Airport data, which commenced in 1993.
