Perth is now just two 35 degree days away from eclipsing a record that has stood for over three decades. Based on current forecasts, this could happen as early as Monday. 

On Saturday, the mercury at Perth soared to a sweaty 38.8 degrees. This marked the 30th day in excess of 35 degrees so far this summer. The highest on record is 31 days, which was recorded in the summer of 1977/78. The forecast is for Sunday to reach 36 degrees, and Monday 35 degrees. Should both these forecast eventuate it would equal, then surpass, the 31-day record.

It is likely that the record will be broken by several days, with top temperatures likely to linger around the mid-thirties each day for the rest of summer. Based on the current forecasts, by the end of summer there will have been at least 36 total days above 35 degrees.
