Give me upper 70's to mid 80's, crisp clean clear dry Canadian air, and a breeze blowing off the lake to keep the bugs moving along. This is the kinda weather I love when at the lake - sweatshirt, in the admirondack chair on the dock, with several good books!!
July fourth several years back - temps hit upper 90's and it was MISERABLE!!! We had 25 people up and NOBODY wanted to be on the boat, or on the beach - was brutally hot and humid. We all were in the water from 9am until about 9pm!!
This is the weather that I recall as a kid - cool crisp nights with a bonfire, and sunny crisp days on the lake!
Sorry folks - hope that heat and humidity stays away!
