I (mostly) enjoy the work, and don't mind the heat too much, but it slaughters me working in the direct sun and heat. I've been framing up the extension roof all week, and there's nowhere to escape the sun so it's been grim.
It was delayed two weeks due to the heavy rain, then when I could get to it the sun was a killer. Then yesterday had to rush around on the hottest day wrestling with 5m x 8m tarps trying to get it all covered ready for the rain again!
Perfect outdoor working weather for me is a dry bright day in Autumn or Spring.
