That's only about 79 degrees F, and it frequently is hotter than that here in the summer. We even get into the 90s (for two or three days) and even exceed 100 degrees rarely. And we're right next to Canada, eh. I think the difference may be the humidity. It's 47% here right now, and rarely exceeds the 40s.
When I was a boy in northern Ohio we often had 90 degree temps with 90% humidity, and that was brutal without air conditioning,
