119F in the shade. That translates to a 'feel like' temp of 134F in the full sun.
My commute is of course not in the shade, but on 170F pavement.
I've lived in Houston too and ridden there during several summers (104F, 95% humidity type) and can't say that either dry vs. wet is worse or better. At least one can go further in the humid highs, although one may feel hotter.
