In subtropical Oz, winter's not an issue. If I'm batch annealing, then I just have to make sure the crockie's well and truly heated before I start working.
Summer work can get really hot, though - I'm in a tin garden shed, but I have a fan at my back, which helps. I finally also got around to putting towelling on my duct-tape armrests, which helps immensely. Sticking to armrests isn't a good thing at all!
Weather-wise, I do have an issue with really high humidity, though. When it's really wet air, accompanied by heavy rain, for some reason, the Effetre Clears soot up much more easily. I can't explain it - but I suspect it's to do with how the HH works in these conditions. The variables involved, however would be mind-boggling, so I don't think much about it too much
