After months of warmer than average temperatures, southwest WA is seeing a colder than average week.
The mild beginning to the week in the southwest has been caused by cooler southwesterly winds behind a cold front which marched across the state on Monday.
This comes after a warm October, with the average maximum temperature of 26.2°C, nearly 5°C above average.
While the southwest of the state is enjoying mild spring temperatures, the cooler airmass did not make its way to the north of the state.
