January golf in San Jose means playing in the coldest conditions the calendar offers here — a 59°F average high that sits right at the lower edge of the ideal 60–80°F window. That number alone won't wreck your scorecard, but pair it with an average low of 44°F and you're starting early rounds with hands that take four or five holes to warm up. Club distances will run short, especially on morning tee times, so expect to add half a club or more on approach shots.
The bigger scorecard threat is the rain. January is the second-wettest month of the year with 11 precipitation days, meaning better than one-in-three rounds has a real chance of wet fairways, soft greens, and plugged lies in bunkers. The upside is wind: at 9.4 mph peak, January is the third-calmest month of the year, so when the rain holds off, ball flight stays predictable and scoring conditions are more forgiving than the wet turf might suggest.
Book midday tee times — 10 AM to noon — in January specifically to let the 44°F overnight low climb toward the afternoon high before you play; early morning rounds in this month will cost you meaningful carry distance. With 11 potential rain days, checking a 48-hour forecast and holding a flexible cancellation window is more important in January than in almost any other month here. See how conditions rate hour by hour on our playability scale.
January and December share identical temperatures — both average a 59°F high and a 44°F low — but January is meaningfully drier, dropping three precipitation days to 11 versus December's 14. Moving into February, you gain 3°F on the average high and shed another three rain days down to 8, making February noticeably more playable even though the peak wind ticks up slightly to 10.2 mph from January's 9.4 mph.

January averages 11 precipitation days, making it the second-wettest month of the year in San Jose. Courses can be soft and slow after back-to-back rain events, so calling ahead the morning of your round to ask about conditions is worth the effort. Wet fairways and saturated rough are a realistic expectation on any given January day.
The average high of 59°F is technically the coldest the city sees all year, just below the 60–80°F ideal range, but it's rarely unplayable. The main practical effect is reduced carry distance — plan to club up on most approach shots, particularly before noon when temperatures are still climbing from the 44°F overnight low. Dress in windproof layers and the cold alone shouldn't add more than a stroke or two to your round.
