When to Go
From October through early May, Houston's weather is ridiculously pleasant (barring the rare late-season hurricane). Once summer rolls around, though, four long months of extremely high temperatures (and humidity) bake the city, and Houstonians jump at any opportunity to get out of town. Air-conditioning here is arctic-grade and widespread; almost every indoor space you visit will have a controlled climate (even the underground tunnels downtown). Festivals are timed to occur during Houston's more livable months (namely, the spring).
