I wish 40C in Toronto felt like 25C.Over here on the coast we get down to about -1 to -2 normally, occasionally it will get down to -10 or so. Big difference however it is normally a very damp cold rather than the dry cold you tend to have, or so I am told from what the sister in law. It was the same when I was on holiday in the East (Toronto area) a long time ago, temps were touching 40 degrees but to me it didn't feel that overly warm, here if we get 25 degrees we know about it
Yes, correct you are regarding exerting effort.It did to me, in fact I would say it felt cooler than 25 degrees here. Granted I was on holiday and not having to work in it but it felt just like an electric fan heater blowing on me.
That sounds so 1960s Canadian summer at the beach.I did have to push a car one time we went to the beach (one of the lakes) as we were running out of petrol and stuck in queues of traffic.
