Hot as balls in Houston these days, heavy rainstorms only make it more humid. But I'll still squeeze in a walk whenever I can, which begets me nothing but strange looks from the Houstonians in their cars. Nobody really walks around these parts, unless they are leashed to a dog.
I find that the less I walk, the less I'm able to think. No earbuds/podcasts/music for me thank you very much (except of course when I'm at the drawing board in the studio).
