What to Wear in San Antonio in Fall: Month-by-Month Outfit Guide
San Antonio in fall sits in the 60 to 80°F range. This is the layer-by-layer outfit guide for San Antonio's fall weather — what to wear, what to pack for a visit, and the local context that shapes the recommendations.
WHAT TO EXPECT
60 to 80°F is the typical range for San Antonio in fall (September, October, November). October through November. 70-85°F. The temperature range is the headline; what you actually feel depends on humidity, wind, and what indoor spaces you'll cycle through.
THE FOUNDATION LAYER
A standard cotton or synthetic shirt is fine. The base layer is conversation-piece territory — not survival.
THE MID LAYER
Optional. A light cardigan or unstructured blazer handles cool mornings and air-conditioned interiors.
THE OUTERWEAR
Trench coat, light wool blazer, denim jacket, or a packable shell. Layer the outerwear, don't replace it.
ACCESSORIES
A scarf for cool mornings, a packable umbrella, and shoes you can walk in for an hour.
WHAT TO PACK FOR A TRIP TO SAN ANTONIO IN FALL
Three layer permutations covering the 60 to 80°F range, plus accessories. If your trip spans the season's edge (early March or late November), pack toward the cooler end of the range — overestimating warmth is easier to recover from than underestimating.
LOCAL CONTEXT
Similar climate to Houston but slightly drier inland. Heat index manages most of the summer. AC contrast indoors is intense.
