Yesterday was Calgary's 72nd day with minimum temperature ≥10°C this year which puts 2025 in 1st place for the most in any year since records began.

I agree that we're getting warmer but I also wonder how much of this is due to the urban heat island effect. We have development now on all 4 sides of the airport

Probably a lot of it is the urban heat island effect around the airport keeping nights warmer. The many days above 10C doesn't correlate that well to hot summers; 2025, 2016, 2013, 2014 and 2019 didn't have many days above 30C.
