| Average December Weather | |

| Rainy days | 11 / mo |
| Avg peak wind | 11.2 mph |
December's numbers translate directly to scorecard consequences worth understanding before you book. A 66°F average high sits right at the lower edge of the ideal 60–80°F scoring window, so morning rounds starting near the 48°F average low will mean stiff hands and shorter carry distances — expect to club up one, sometimes two, compared to your summer yardages. The 18°F daily swing is the real story: start bundled and plan to peel layers by the back nine.
The silver lining is in the precipitation and wind columns. Eleven rainy days ties for the driest month of the year alongside January and February, and the 11.2 mph peak wind ties October and November for the second-calmest peak wind of the year. That combination means firm, fast fairways and minimal wind penalty on approach shots — two conditions that genuinely help scoring for mid-handicappers who lose strokes to soft lies and crosswinds most of the year.
With morning lows near 48°F, booking a tee time no earlier than 9 or 10 AM lets the temperature climb several degrees and gives any overnight moisture time to burn off fairways — critical when December already logs 11 wet days that can leave cart paths slick at dawn. Demand is lighter than spring and fall, so late-week afternoon slots are often available at reduced rates without sacrificing playable conditions.

November plays noticeably warmer, with a 71°F average high — 5°F above December — and two more rainy days, so December is actually drier despite feeling colder. January drops another 3°F to a 63°F high while adding 0.8 mph of peak wind, making December the more comfortable of the two winter months on both the temperature and wind fronts. If you're weighing which shoulder-season month to visit, December sits in a narrow sweet spot between November's mild warmth and January's sharper chill.

December qualifies as shoulder season, with a 66°F average high that keeps conditions playable but noticeably cooler than spring or fall. It ties January and February for the driest month of the year at 11 precipitation days and shares the second-calmest peak wind reading at 11.2 mph alongside October and November, so cart-path conditions and wind interference are both favorable. The main adjustment is the cool morning temperatures near 48°F, which require extra club selection and proper layering.
The average low hits 48°F, meaning early-morning tee times can feel genuinely cold — cold enough to reduce ball compression and shorten carry by several yards per club. The average high climbs to 66°F, so by midday conditions are more comfortable, but the 18°F daily swing means dressing in removable layers is more important in December than almost any other month on the San Antonio calendar.
