May has kicked off with unusually warm weather in southwestern parts
of Western Australia, after many parts had record breaking heat during
Perth had its hottest April in 116 years of records, with an average
maximum of 28.5 degrees. This has only happened three times since
records began. In terms of minima it was the capital's second hottest
April on record, second only to April 1962.
In the Great Southern District Narrogin, Brookton, Corrigin and
Pingelly all broke records for minimum and maximum temperatures in
Elsewhere, Esperance hasn't had a hotter April in at least 20 years,
while for Medina you need to go back at least 26 years. It has been
nearly a decade since Kalgoorlie had such hot April days.
May has brought the unusually warm weather with it, after what was a
very hot night.
It was the hottest May night in more than ten years for Kalgoorlie and
Southern Cross Airport, where it stayed above 18 degrees all night.
For Laverton Airport, Esperance and North Walpole is was the hottest
May night since 2005.
Inland areas warmed up quickly after sunrise. By 1pm Laverton had
reached 35 degrees, their hottest May day since at least 2005. Today
has also been Kaloorlie's hottest May day since 2002, reaching 31.
For those towns closer to the coast, an approaching low and trough
brought cloud and showers, keeping temperatures at bay.
This system will cause showers to increase to rain during Wednesday
night and Thursday morning. There is potential for more than 50mm in
parts of the southwest land division, much of which had well below
average rainfall last month.
As the low and trough move east, the southwest land division can
expect a few cooler days, with temperatures in the low-to-mid 20s.
Inland areas are likely to remain hot as a hot air mass lingers.
