Did you find it rather warm as you woke up this morning, perhaps your morning run felt more like it was still summer?
Much of Melbourne just experienced their hottest May night on record.
In Scoresby the temperature never fell below 19C. At this time of year it's usually around 8C - this morning was more than 10 degrees above average!
Even Coldstream didn't live up to its name with 17.7C earlier today. The average for May is a much chillier 5C.
Most of the observing stations in the Melbourne area set a new May record this morning:

The city nearly set a new record, but not quite.
When I woke up this morning, I thought we had done it. At 6:30am it was 18.4C. I jumped out of bed getting ready to share this extraordinary news, but realised I had to wait - as the temperature hadn't finished falling yet.
The city's overnight low wasn't recorded until 8am this morning, nearly a full hour after the sun began to rise.
We often see the coldest part of the night after sunrise. All through the night we lose the day's heat to the atmosphere, and the first rays of sun aren't strong enough to outweigh this cooling.
We finally stopped falling at 17.5C and in the 169 years of observations there has only been one May night that was warmer. The record remains at 18.0C set in 2009.

We're experiencing well above average temperatures during the day as well. Yesterday reached 24.5C in the city and today is moving past 26C.
The average for this time of year is just 17C, so this is significantly warmer than what we usually experience.
The record for May is 28.7C and we won't quite make it that high.

This is the end of this extraordinary stretch, as a cool change arrives tomorrow. A cold front crossing the Bight will pass through, bringing an end to the 'summer-like' temperatures for now. There is a brief burst of showers on Wednesday, as temperatures fall. By Thursday morning it should be back down in single digits and it's even cold enough to snow in Tasmania down to 500 metres!
