Where I am in Aus we'd be lucky to see 0C once or twice a year at most in the middle of the night in the middle of winter for maybe an hour. I put on long pants or a sweater under 20C.
In the UK this summer we've been lucky if it hits 20°C this year. I've been in shorts all summer. We had a nice June but since then it's been cloudy and rainy. Regardless I've been in shorts since June. Winter is typically a single figure affair so summer is always very much welcomed. Feels like we haven't had one this year :(
The oceans on this side of the planet are about to see record temps, fingers crossed we don't see ecological collapse of the Great Barrier Reef and record fire seasons.
