What to Wear in San Antonio in Spring: Month-by-Month Outfit Guide
San Antonio in spring sits in the 70 to 85°F range. This is the layer-by-layer outfit guide for San Antonio's spring weather — what to wear, what to pack for a visit, and the local context that shapes the recommendations.
WHAT TO EXPECT
San Antonio in spring — March, April, May. March through May. 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
Lightweight, breathable single layer. Linen, cotton voile, or technical synthetic.
THE MID LAYER
Skip it. San Antonio spring doesn't need a mid layer.
THE OUTERWEAR
None. The "outer layer" in San Antonio in spring is air conditioning. Carry a light wrap or button-down for over-AC restaurants.
ACCESSORIES
Sun hat, UV-rated sunglasses, sandals or breathable sneakers, and a light scarf for over-AC interiors.
WHAT TO PACK FOR A TRIP TO SAN ANTONIO IN SPRING
Three layer permutations covering the 70 to 85°F range, plus accessories. If your trip spans the season's edge (late February or early June), 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.
