All Months
March through May brings perfect weather — sunny days in the 70s and 80s, minimal humidity, and everything in bloom. This is peak season, so expect higher hotel rates and crowded attractions.
Fall (October-November) offers similar weather without the spring break crowds. October averages 77°F, and you'll catch the State Fair of Texas if you visit in early October. Hotel prices drop slightly compared to spring.
Winter stays mild by most standards — highs in the 50s and 60s, with occasional cold snaps. December through February see the lowest hotel rates, but some outdoor attractions have limited hours.
Avoid June through September unless you enjoy sweltering heat. Temperatures regularly hit 100°F, humidity makes it feel worse, and you'll sprint between air-conditioned buildings. Pool weather, sure, but walking around becomes miserable. July averages 96°F with oppressive humidity.
