Forecast

The barometric pressure in Perth is generally high. It ranges from 1013 to 1023 hectopascals. This is due to its location in the subtropics.

Perth is surrounded by the Indian Ocean to the west. This leads to a high pressure system developing over the city. The ocean's warm waters heat the air. Heated air rises, creating low pressure near the surface. As a result, air from higher altitudes moves in to replace it.

To the east of Perth lies a vast desert. This desert is hot and dry. It creates a region of low pressure. As a result, air from the Indian Ocean moves towards the desert. This movement of air affects the atmospheric pressure in Perth.

Perth's coastal location and surrounding landscape influence its weather. The combination of the ocean and desert creates a unique pressure system. This system affects the city's weather patterns throughout the year.
