Most golfers assume January in Boise means the courses are locked up and snow-covered — the reality is more nuanced, and occasionally more playable than expected. The city sits in the high desert, so hard freezes are common and morning tee times with a 26°F low are genuinely brutal, but afternoons can reach 40°F, which is at least functional if you dress properly. That 14-degree daily swing matters a lot on the course.
The bigger surprise is the precipitation. January ties December as the wettest month of the year at 14 days of measurable precip, and in the high desert that often means a mix of rain, sleet, and snow rather than one predictable form. Courses that are open at all will likely have frost delays and soft, slow fairways. Wind averages 11.9 mph at peak — not severe on its own, but paired with near-freezing temps it changes the equation fast.
Book afternoon slots starting no earlier than noon to let frost clear and give temps a chance to climb toward the 40°F high — morning rounds at 26°F are playable in gear but frost delays can eat into the first hour unpredictably. Call ahead the day before; with 14 precipitation days spread across the month, conditions can shift quickly and some courses close on short notice after overnight freezes. See how conditions rate hour by hour on our playability scale.
January and December are essentially identical on paper — same 40°F high, same 26°F low, same 14 precipitation days, with January only slightly windier at 11.9 mph versus December's 10.9 mph. Neither month is meaningfully better for golf; if you played December, January will feel the same. February offers the first real improvement: highs climb to 44°F and precipitation days drop to 12, so if you can wait, February gives you a modest but genuine edge.

Some courses stay open through January, but conditions are far from guaranteed. With an average high of only 40°F, lows around 26°F, and 14 days of precipitation — the wettest month of the year — expect frost delays, soft fairways, and occasional temporary closures after storms. Calling ahead the day before is essential.
The average high reaches 40°F, but mornings start around 26°F, and with peak winds averaging 11.9 mph the wind chill can make early rounds feel significantly colder. Afternoon rounds are the most reasonable window, though even then you're well below the 60–80°F comfort range most golfers prefer.
