If you are stubbornly convinced that it is even colder today than the weather forecast is suggested, rest assured it's not just you.

When wind chill and moisture is factored in, the past weekend – already the coldest in Perth for eight months – felt up to six degrees colder than the official readings and Monday has so far brought only the slightest relief.

Saturday and Sunday together marked the coldest pair of days since September, with Sunday morning the coldest morning since September, Weatherzone meteorologist Tristan Meyers said.

There was a drop of nearly eight degrees between Saturday morning's minimum and Sunday's, with mainland minimums ranging from 2.1 at Jandakot to 10 degrees at Hillarys overnight.
