Best time to visit San Antonio

San Antonio is a city of two halves. February scores 91 and July scores 43 — a 48-point swing, which is the difference between a holiday and an endurance test. The month you pick matters more here than almost anywhere. 4 of the twelve months sit within ten points of the best, so there is more than one right answer.

August is the warmest month at 36.7 °C and January the coolest at 17.7 °C — a 19 °C spread across the year. 166 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season. 9 nights a year dip below freezing.

There is a real wet season here. May, June, July and September carry the rain — up to 10 wet days in a month — while January, February, April, November and December drop as low as 5. That 5-day gap is the biggest single difference between a good month and a bad one in San Antonio, and it moves further than the temperature does.

Daylight runs from 10.3 hours in winter to 14 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are February, November, March. The one to think twice about is July. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
