Rain is the one variable that defines golf in San Diego in January. Temperatures are comfortable — highs of 63°F keep conditions playable, and the 16°F daily swing means mornings start cool but rarely feel punishing. Winds average 11.1 mph at peak, the fourth-calmest reading of the year, so wind is seldom the problem.
The issue is precipitation. January ties February as the second-wettest month on the calendar at 8 rainy days. That doesn't mean every round gets rained out — it means you need a flexible schedule. Book a tee time, watch the forecast, and have a backup day in mind. Courses stay green and uncrowded by San Diego standards, and when a January window opens up, conditions rank among the best San Diego offers in winter.
With 8 rainy days spread across 31 days, roughly one in four days carries real rain risk — book early in the week and monitor short-range forecasts so you can shift your tee time to a drier window rather than cancel outright. Morning slots often clear faster after overnight showers than afternoon slots that catch developing coastal weather. See how conditions rate hour by hour on our playability scale.
December edges January by just 1°F on the high (64°F vs. 63°F) and sees one fewer rainy day, making it marginally drier and slightly milder — though the difference is barely noticeable on the course. February matches January almost exactly: the same 8 precipitation days, a nearly identical temperature profile, but with winds picking up to 12.4 mph compared to January's 11.1 mph. If you're choosing between the three months, January is no warmer than its neighbors; December is the calmest of the three on wind, and January sits between December's 9.9 mph and February's 12.4 mph.

January carries a Peak season badge for good reason: highs of 63°F and winds that top out around 11.1 mph make for comfortable, low-wind rounds when skies cooperate. The caveat is 8 precipitation days — tied for second-most in the year — so flexibility in your schedule matters more this month than any other playing condition.
January averages 8 days with measurable precipitation, the same as February and tied for the second-most rainy days of any month in the year. Rain tends to arrive in multi-day pulses rather than steady daily drizzle, which means a well-timed tee time mid-week between systems can deliver perfectly firm, uncrowded fairways.
