A brief shift to cooler temperatures is anticipated in Perth later this week, while elevated temperatures are projected to persist across much of Western Australia. A weak weather system is moving through the southern region of Western Australia, contributing to this temporary change.
Western Australia Overview
High temperatures are expected to continue across most of Western Australia throughout the week. Severe heatwave conditions are forecast for segments of the southern, central, and northern parts of the state, with some areas potentially experiencing extreme heatwave conditions. Temperatures in the northern regions are predicted to moderate slightly by the end of the week.
Inland areas of the state may experience thunderstorms as a west coast trough progresses eastward. The presence of dry lightning and gusty winds could elevate the risk of fire activity in these regions. Seasonal showers and storms are also forecast for the Kimberley and Pilbara areas, with storms in the Pilbara largely expected to be dry.
Perth Specifics
In the Perth CBD, conditions are forecast to be sunny, stable, and warm through the midweek, with maximum temperatures around 30 to 31 degrees Celsius. Cloud cover is anticipated.
A new ridge is expected to establish on Thursday, introducing a south-westerly airflow over Perth, with a maximum temperature of 29 degrees Celsius. Friday is forecast to have partly cloudy conditions with a maximum of 30 degrees Celsius, followed by a warming trend into the weekend.
The cooler air will be most noticeable during the early parts of the day, with afternoons warming rapidly under predominantly clear skies. Winds are expected to be light to moderate, and no significant rainfall is predicted for the metropolitan area. The anticipated cool change is short-lived, with temperatures expected to rise again soon after.
