RECORDS have tumbled across Western Australia as a short lived heat wave makes its mark.
On Monday many parts of the southwest sweltered as the mercury soared into the 40s. Yesterday however, the mercury smashed further into the high 40s, destroying some December records.
Overnight, it was an uncomfortable one for many as minimums stubbornly refused to drop anywhere near average. Some places such as Karnet dropped to only 23 degrees, their warmest December night since 1965.
Carnamah barely dropped to 29, 13 above average and their warmest December night since 1940, or the warmest night since 1991.
Through today, the trough responsible for drawing the intense interior heat south moved eastward. The 'cool' change that arrived in Perth in the late morning held the maximum back at a mere 39 degrees.
The main heat was further east, affecting the Great Southern, Central Wheatbelt and South Coastal.
The hot spots were:
- Morawa - 47 degrees, hottest in December for 12 years.
- Esperance - 45 degrees, 21 above average, hottest day since at least 1991.
- Hyden - 46 degrees, 14 above average, hottest in December since 1970.
- Dalwallinu - 45 degrees, 12 above average, hottest in December since 1957.
