I spent wednesday in an attic wiring up some ceiling fixtures. I didn't have a thermometer but I would bet the heat exceeded 120 degrees. I could only spend 10-15 minutes up their at a time and I would come down to 80 degree AC and it would be such a relief. My shirt was soaked the whole time and in 2 hours I drank nearly 2 gallons of water. Heat is nothing to mess with, everyone be careful.
