January in San Antonio, TX: shoulder season for golf — playable with smart tee time selection. Best tee times: late morning to early afternoon after dew burns off.
| Average January Weather | |

| Avg peak wind | 12 mph |
January sits at the cold end of San Antonio's golf calendar — the only month where the average high doesn't crack 65°F. That 63°F ceiling means morning rounds can feel genuinely chilly, with lows down around 44°F and a 19-degree daily swing that demands layers you'll be peeling off by the back nine. Tee times after 10 AM let the air settle closer to the mid-50s before you commit to a club.
Still, the shoulder-season badge here is earned by what January gets right, not just where it falls short. Precipitation days tie December and February at 11 — the joint driest stretch on the annual calendar — so firm, playable fairways are the rule. Peak wind averages 12 mph, third-calmest of any month, meaning the cold rarely comes with the kind of gusts that wreck shot shape. If you dress for it, golf in San Antonio in January is more workable than the temperature alone suggests.
Book mid-morning slots (10 AM–noon) rather than first light; the 19°F daily swing means a 7 AM round starts near 44°F, and an extra two hours adds meaningful warmth without costing you daylight in January's shorter days. Weekend morning tee sheets tend to open up in January because casual players avoid the cold, so last-minute same-week bookings are more realistic than in spring or fall. See how conditions rate hour by hour on our playability scale.
January is 3°F cooler at the high than December and 4°F cooler than February, making it the clear coldest point in the three-month window. Precipitation holds steady across all three months at 11 days each, so there's no meaningful rain advantage gained by waiting. Wind ticks up slightly as you move through the window — from 11.2 mph in December to 12 mph in January to 12.7 mph in February — but the differences are minor and unlikely to change how you play.

It depends on your tolerance. Average highs reach 63°F, but mornings start near 44°F, so an early tee time genuinely feels cold. Afternoon rounds in the upper 50s to low 60s are comfortable with a mid-layer. The trade-off is that January's 12 mph peak wind is one of the calmest of any month all year.
The climate average shows 11 precipitation days for the month, which is actually tied for the fewest of any month on the calendar alongside December and February. That said, 11 days spread across 31 means roughly one in three days sees some measurable rain, so checking a 72-hour forecast before booking is still worthwhile.
