San Antonio in July

March through May gives you perfect weather – highs in the 80s, cool evenings, and Fiesta season in April. This is peak tourist season, so book hotels early and expect crowds at the Alamo. Fall works beautifully too, especially October and November when temperatures drop to the 70s and humidity finally breaks. December through February stays mild – perfect for exploring the missions without sweating through your shirt. But here's the catch: summer is brutal. June through August sees daily highs over 100°F with crushing humidity. Locals retreat indoors from noon to 6pm. Winter brings occasional freezes that shut down the city – San Antonio doesn't handle ice well. Spring break crowds in March can overwhelm downtown, especially around the Riverwalk. For the best experience, aim for late October through early December or late February through March.
