Perth has sweltered through its hottest February night in two years.

The mercury hovered above 30C in Perth until 9pm last night, falling to a minimum of 24.4C at 6am.

Conditions were even balmier on the coast, with Swanbourne recording a low of 26.5C just after 6am.

Pearce barely dropped below 30C, reaching 28.6C at 6am before returning to 32C by 8am.

Morawa in the state’s mid-west registered a 28.9C minimum at 3.30am, while in the Kimberley, Argyle recorded 27.3C at 5.20am.

Bureau of Meteorology officer John Relf said another 40C-plus maximum was not out of the question today.

“It’s heatwave day number four today,” he said. “But for those people who do like cooler weather, there is light at the end of the tunnel.

“The forecast for Sunday is 26C and a shower or two.”

The highest February minimum on record for Perth was 29.3C, set in 1898, 1933 and 1962.

Watercorp said 1.2 billion litres of water passed through the Integrated Water Supply Scheme from 9am Sunday to 9am yesterday.

The IWSS services Perth, Mandurah and parts of the South-West and Goldfields.

Watercorp spokeswoman Clare Lugar said the 24-hour usage was equivalent to 555 Olympic swimming pools – 95 pools over target.

“1 billion litres is basically Patersons Stadium filled to the top of the goal posts,” she said.

“We knew it was going to be a significant day but it was quite a bit worse than we expected. We can do better.”
