2.4°C northwest of Joondalup
At Wanneroo around 20 km northwest of Joondalup temperatures dipped to 2.4°C this morning.
The low temperatures were much lower than they were at other locations around Perth and likely because the boundary layer decoupled over the station area with light winds, excellent radiational cooling leading to the formation of a nocturnal temperature inversion.
Over the south of the state, frost was potentially observed in areas as temperatures dipped to -0.4°C at Wandering.
Temperatures at the Mt Lawley site dipped to 10.9°C.
