Even the eighty year old folks I have asked have never seen summer weather like we've had this year this in southeastern New Brunswick, Canada. So far this summer, we've only had about a half dozen days of 30C and above. The rest of it has been 10 to 15C overnight and 20 to 25C daytime, RH around 50 to 80%, and little rain. Don't expect it will last much past the new moon, though.
The New Brunswick shore of the Northumberland straight is a big tourist draw because of the warm waters and beautiful beaches but I've seen a lot of them walking around with jackets and long pants and disgusted looks on their faces.
