December in Flagstaff, AZ: cool / cold season for golf — expect distance loss and stiff muscles. Best tee times: midday when temperatures are warmest.
| Average December Weather | |
|---|---|
| Avg daily high | 44°F |
| Avg daily low | 26°F |
| Rainy days | 6 / mo |
| Avg peak wind | 11.6 mph |
A 44°F average high sounds manageable until you factor in what it does to a round. Cold air is denser, which means shots fly shorter — expect to club up one, sometimes two clubs on longer approaches. The 26°F average low means early morning tee times are a genuine problem: frost delays are common at Flagstaff's elevation, and a frozen fairway plays nothing like the course listed on the scorecard. Afternoon slots give temperatures a chance to climb, but 44°F is still well below the 60–80°F ideal range, so distance loss is a constant companion all day.
The wind, at 11.6 mph peak, is actually the least of your scorecard concerns in December — it's Flagstaff's 4th-calmest month of the year. The real variable is that 18°F daily temperature swing. Layer management between holes matters as much as club selection: what plays reasonably in the early afternoon can feel arctic again by the time you reach the back nine.
Book the latest available morning tee time — late morning or early afternoon — to avoid frost delays and let the temperature climb as far as the 44°F average high allows. Same-day and last-minute slots open up frequently in December because demand drops sharply, so you rarely need to book far in advance, but calling ahead to confirm frost status that morning is worth the two minutes.

December drops 7°F from November's 51°F average high, and six precipitation days versus November's four means slightly messier conditions — frozen or wet ground becomes a more regular factor. Compared to January, December is actually the milder choice: January's average high falls another 5°F to 39°F and brings nine precipitation days, three more than December. Wind is essentially a wash across all three months, hovering within 0.2 mph of each other.

Most courses operate reduced hours in December and are subject to frost delays that can push first tee times to late morning. Calling ahead the day before is essential because a 26°F overnight low almost guarantees frost on exposed fairways and greens. Afternoon availability is generally more reliable than early slots.
Two factors stack against distance in December: cold air density increases at altitude, and the average high of 44°F is well below the 60–80°F range where ball compression and carry are close to normal. Plan on losing meaningful distance — clubbing up one to two clubs on mid- and long-iron approaches is a practical baseline, not a worst-case estimate.
