August 2021:
After the second wettest July on record, the Mt Lawley site saw the second driest August on record and the driest in 13 years.
Only 56.6 mm of rain fell which was less than half of the August average. By contrast, July was the Mt Lawley site's second wettest on record which saw 271.4 mm of rain.
It was also a warmer than usual August. Pearce RAAF also saw the highest August daily minimum temperature on record, 16.8˚C.
It's actually not uncommon for unusually wet July's to be followed by unusually dry August's. July 1995 was the Mt Lawley site's wettest July on record, however, August 1995 had a monthly total more than 40 mm below the average for August. Perth's driest August on record, August 1902 which only saw 11.8 mm of rain had followed a July which saw more rain than July this year. Perth's wettest July on record, July 1958 which saw some 425.1 mm of rain was followed by an August monthly rainfall of only 57.1 mm , around 80 mm below average.
Furthermore, July 1918 saw some 18 consecutive days WITHOUT rain and followed an unusually wet June which had some 266.7 mm of rain. October 2020 saw the longest October dry spell in 138 years, this was followed by the wettest November on record by a large margin. Perth's Airport's longest dry spell on record ended with the March 22 2010 hailstorm.
