Dang, is it ever cold here in Massachusetts. There is a lot of wind but I am definitely NOT thinking about windsurfing. Actually, that's a lie. I AM thinking about windsurfing, but only in a mournful, unrequited love kind of way. If it got up to 4.5 Celsius (40 Fahrenheit) I might don the drysuit and give it a go, but this below-freezing stuff is just not my style.
I reckon now would be a good time to post the final results of my "What's your minimum air temperature for windsurfing or kiteboarding?" survey. Here they are:
Looks the most common temperature cut-off is between 10 and 7 Celsius (50 and 45 Fahrenheit), but there is a significant minority of insane people who claim to ride in sub-freezing weather. Must be Canadians and Europeans.
