Houston
Houston is the second-most southern city on our P0 list, behind only Miami. At 29.76°N the solstice sun climbs to 84° at noon and the heat index sits at 105–110°F for weeks at a stretch — and the city has already, partly, given up on the surface. Seven miles of climate-controlled tunnels run under downtown for a reason. Our model is for the parts above ground that haven’t surrendered yet.

The short downtown surface walk people actually make. Discovery Green’s oaks for the first block, then the convention-center overhang.
