If you think of 20°C as super conveniently being room temperature (68°F) and use that as an anchor; you can then, within about +/- 40°F, think of every +/-5°C as about +/-10°F. For example:
20 - 10 = 10°C (50°C) is approx. 68 - 20 = 48°F
20 - 20 = 0°C (32°F) is approx. 68 - 40 = 28°C
20 + 10 = 30°C (86°F) is approx. 68 + 20 = 88°F
That is, if you use 20°C/68°F as an anchor, take the difference in Celsius from 20°C, multiply that by two, and add it to 68°F, you have a decent approximation of what the temperature is in Fahrenheit. That’s assuming 20°C is the only anchor you have and that you never want to learn what other temps are – just a compact, minimal-memorization algorithm that gets you close enough for the rare times you need it.
(The real algorithm is that x°C =(y°F-32) ÷ (1.8))
Our weather has always been weird. A month of frost still, but daytime temps can get upwards of 30c. Snowed a foot yesterday, chinook today, most of the snows melted, but what’s in the shade and protected from the wind is still there.
All snow doesn’t instantly melt above freezing just like all the water in your pot doesn’t instantly evaporate when you turn on the heat. The temperature can rapidly fluctuate up above freezing while there’s still a bunch of snow on the ground, and that takes a while (sometimes days) to melt. Melting is affected by factors like shade, snow depth, etc., so while the picture shows no snow, there might be plenty surrounding it – which could be expected accounting for survivorship bias (namely that the lovebugs are unlikely to be lovin’ on top of a foot of snow).
68°F.

Ambient air might be above freezing, but the piles of snow in the shade are still below freezing.
At 20°C!? Is this some kind of Df climate thing that I’m too Cf to understand?
Yup. The big piles don’t melt until July.
Don’t forget the piles from the ice rinks never melt!
Welcome to Chinooks in Calgary.
My condolences. That does not look fun in summer.
Gets funner, we have Microclimates too. Some communities can grow gourds, while others are just shit out of luck without greenhouses.
I’m oversimplifying, but gets the point across.
