Like Scott T, I'm a Sunbelt resident - but I do live in the Southeast, not the
Southwest - so it's a WET heat in the summer (thick; you can wear it sometimes), and
that air conditioned train building calls to me more in the Summer than Winter - it can
get cold out there (we have something of a Winter, too), and my space heater can take a while to warm things up. Basements? Heard of them, but maybe it's just an urban legend.
Of course, the season is mostly irrelevant, as, in actuality the weather here seldom keeps us cooped up for long. Hurricanes can be inconvenient. Yup.
Fun Fact: Mobile (where I am), on the Gulf Coast, gets 65" of rain per year - typically, and actually, the wettest urban area in the US. Seattle, of gray skies fame, gets a little under 40" per year, as I recall.
But ours tends to come down in a 30-minute "gully washer" - then the sun comes back out.
