Most golfers arriving in San Antonio in May expect something close to ideal spring golf — warm but not brutal, breezy but manageable. The reality is more complicated. May is actually the wettest month of the entire year here, averaging 21 precipitation days, which means rain interruptions are a genuine planning concern, not a passing risk. Temperatures are comfortable in the morning, with lows around 69F, but afternoon highs reach 86F — warm enough that an early tee time matters more than most visitors anticipate.
The 17F daily swing between high and low is the other surprise. What starts as a pleasant 69F at dawn can feel like a different course by the back nine. Winds average 13.3 mph at peak, the third-windiest month of the year, so club selection in the afternoon gets genuinely tricky. Golf in San Antonio in May rewards flexibility and early starts more than any other spring month.
With 21 precipitation days, booking a tee time early in the morning significantly reduces the chance of a rain delay — afternoon thunderstorms are the dominant pattern in May. Given the limited cancellation windows many San Antonio courses enforce, locking in a refundable or reschedulable rate is worth the extra step this month. See how conditions rate hour by hour on our playability scale.

Yes — May averages 21 precipitation days, making it the wettest month of the year in San Antonio. That doesn't mean it rains all day, but afternoon and evening storms are frequent enough that you should treat rain preparation as standard, not optional. Morning rounds are substantially less likely to be interrupted.
The heat alone isn't the main obstacle — an 86F average high is warm but manageable, especially compared to June's 93F. The bigger issue is that the 69F morning low climbs quickly, so rounds that start late can feel significantly hotter by the finish. Staying hydrated and teeing off early keeps May golf in San Antonio well within a comfortable range for most players.
