Perth has sweltered through its second hottest April day on record.
The temperature hit 37.3 degrees in the city just after 1:00 pm this afternoon.
The Bureau of Meteorology's Neil Bennett says that is the hottest Perth temperature recorded for an April day since 1910.
He says temperatures should ease slightly in the coming days.
"We will see a slight drop tomorrow because the trough is expected to sit inland for all of the day so a little bit cooler but still over 30 degrees," he said.
"In fact, we're looking at temperatures staying above 30 right through to Friday."
