December in Mesa, AZ: peak season for golf — great conditions and a wide playing window. Best tee times: mid-morning through early afternoon.
| Average December Weather | |

| Avg daily high | 67°F |

| Rainy days | 6 / mo |
| Avg peak wind | 8.7 mph |
December in Mesa is defined by one variable above all others: the 22-degree daily temperature swing. Mornings start cold — the average low sits at 45°F — and afternoons climb to 67°F, which lands right at the lower edge of comfortable playing conditions. That spread shapes every round. A light jacket at the 7 AM tee sheet is a necessity, not a suggestion, yet you may be pulling it off by the 12th hole.
The wind barely factors in. At 8.7 mph peak, December is the calmest month Mesa sees all year, which means that mid-60s high plays warmer than it reads. Precipitation ticks up to 6 days, the third-wettest month of the year, but spread across a 31-day calendar that still leaves plenty of dry windows. Course conditions stay firm and consistent, and with peak-season demand in full effect, tee sheets fill fast on weekends.
Book morning tee times only if you're prepared to layer up through at least the front nine — temperatures at a 7–8 AM start will be well below 55°F. A late-morning start around 10–11 AM lets the air warm toward the mid-60s while still giving you a full round before the light drops in a short December afternoon.

November runs 9°F warmer at the high and brings only 3 precip days versus December's 6, making it the noticeably easier month to dress for and less likely to lose a day to rain. Moving the other direction, January dips another 2°F at the high to 65°F and adds one more precip day, while wind nudges up slightly to 9.4 mph — so December actually sits in a modest sweet spot between the two for calm, dry conditions. The temperature gap between November and December is the sharpest single-month drop in the cooler half of the year.

It is genuine peak season: afternoon highs average 67°F with winds at just 8.7 mph, the calmest month of the year. The trade-off is chilly mornings near 45°F and 6 potential rain days, so plan tee times for late morning and keep an eye on the forecast.
December averages 6 precipitation days, the third-highest total of any month, which is notably more than November's 3 days. In practice that means roughly one day in five has some rain, but multi-day washouts are uncommon — most disruptions are short-duration and afternoon rounds often escape them entirely.
