I'm on the East Coast (New Jersey) and we're getting hammered w/it right now, so there's no relief anywhere, it seems...
I'm not sure about the east coast of the U.S. but the Canadian east coast doesn't have this kind of heat, especially near the ocean where I'm from....temps in my Nova Scotian hometown right now at 12pm EST:
22 ºC = 71.6 ºF
