Booking tee times in Boise in December requires a different mindset than any other month. With the average high sitting at 40°F and lows dropping to 26°F, playable windows are narrow — typically mid-morning through early afternoon when temps climb toward their modest peak. That 14°F daily swing means a round that starts in a frost delay can finish in conditions that are almost comfortable, so watching the morning forecast matters more than the monthly average.
The wettest month of the year — tied with January at 14 precipitation days — means more than one in every three days sees some form of moisture. Flexible cancellation policies and mid-week slots become strategic assets in December. The silver lining: peak wind averages just 10.9 mph, the calmest reading of any month, so on the dry days that do appear, you won't be fighting a stiff headwind on every back-nine hole.
Target tee times between 10 AM and noon so the low of 26°F has had time to lift — frost holds can push first light slots back significantly, and cart path restrictions often follow overnight freezes. Because cancellations spike when precip days run this high, checking same-week availability at short notice often turns up open slots at courses that otherwise book out; holding a backup date is worth it.

November plays noticeably warmer, with an average high of 48°F versus December's 40°F, and three fewer precipitation days, making it the cleaner shoulder option if your schedule has any flexibility. Moving the other direction, January offers no improvement at all — identical highs, identical lows, the same 14 precipitation days, and slightly windier conditions at 11.9 mph versus December's 10.9 mph. In practical terms, January and December are essentially the same month to play, so there's no benefit in waiting out December hoping conditions reset.

Most public courses in the Boise area remain open in December, but available tee times shrink considerably as courses adjust operating hours around frost delays and early sunsets, and some facilities will close temporarily after heavy precipitation or hard overnight freezes. With an average high of only 40°F and 14 precipitation days, it's worth calling ahead or checking the course's website the morning of your round before making the drive.
Expect cart path–only conditions more often than not, as the combination of a 26°F average low and frequent moisture leaves turf vulnerable to compaction damage. Wind is actually the one mild factor — peak wind averages just 10.9 mph in December, the calmest of any month — so on a clear afternoon between fronts, the air can feel almost still even if the temperature reads in the mid-30s.
