I live in Toronto and we regularly get to 35C with high humidity some summer afternoons: not too much of a problem if ride is <1 hour. Just hydrate (perhaps when you get home).

Or just don't cycle on the hottest days, but only on the 'reasonable' ones.

No one says you have to do so every day.

I live in Texas, where we had 43+ consecutive days of weather over 40C this summer.

I actually don't think the weather is even the limiting factor here in Texas. It's that it's literally unsafe to ride a bike on the vast majority of streets here under fear of serious injury or death.
