What degree numbers do you consider hot/warm/cool/cold/etc?

Assuming I'm wearing a short sleeve T-shirt and shorts (what I consider to be neutral, dressing normally without having to adapt for cold), I'm not especially exerting myself, and other factors like particularly strong wind or humidity aren't affecting my thermal sensations, 10 C is about the coldest I can tolerate for a prolonged period without going "gosh it's chilly; wish I had long sleeves on".  20 C is about where there's no longer a perceptible chill in the air if I'm in the sun and the wind's light - though temps anywhere in the 70s F can still feel slightly cool if I'm in the shade and it isn't humid.  By 28 C, the potential for a cool sensation is virtually absent, and there's usually some extent of a warm sensation.  35 C is about where the feeling of "what a nice day!" starts to be supplanted by "it's hot out!".  While "mild", "warm", and "cool" in that order are my three most preferred from a strictly comfort perspective, that's not to say "hot" or "cold" can't be adapted to or even enjoyable.  My 44 C "sweltering" cutoff is an estimation.  Below -7 C, it isn't just cold - even once I've bundled up, the cold still penetrates my entire body under my clothing and it's just nasty. (That's the temperature below which I will break out the jacket, hat, and gloves even if I am just outside for 10-20 minutes such as walking to and from work.)  Therefore my "easily comfortable" range spans 10-34 C (50-94 F), and my "potentially comfortable" range with clothing adaptations spans -7 to +43 C (20-109 F).

Being from Wisconsin has made me cold-hardy - but that doesn't mean I enjoy bundling up. Any temperature that forces me to wear long sleeves is cold and undesirable. Any temperature that forces me to wear a jacket/coat is frigid and I'd be happier if I never saw it again.
