Warm winter after a May deluge
Perth and the South West are set for a warm winter after the wettest May in nine years, the Bureau of Meteorology says.
The bureau has forecast warmer than average temperatures for June, July and August, when temperatures typically reach a maximum of 21C.
In its seasonal outlook, the bureau says there is an 80 per cent chance the average maximum temperature will be more than 21C and a 60 per cent chance the average minimum more than 9C in Perth.
The south of the State is 80 per cent likely to see a warmer than average minimum temperature this winter.
The bureau says the tropical Pacific is likely to warm in the coming months and the tropical eastern Indian Ocean, which is warmer than usual, is likely to return to its normal temperature.
The forecast follows Perth’s wettest May since 2005.
More than 143.6mm has fallen since the start of the month and there have been 18 rain days – the biggest number since records started 21 years ago.
The lower South West has also recorded a wetter than average month, where many areas recorded between 200mm and 300mm of rain.
Donnybrook has recorded 264mm of rain which is the third biggest rainfall in 113 years.
