December marks the bottom of the temperature curve in St. George. The average high sits at 53°F — the coldest of the year, tied with January — while lows drop to 35°F, so that 18-degree daily swing matters more than any single number. Tee off too early and you're nursing stiff hands; wait until midday and conditions are reasonable. Wind, at least, is not a problem: December's 6.4 mph peak is the calmest reading of the entire year, which takes one variable off the table.
Six precipitation days make this the fourth-wettest month on the calendar, so rounds aren't guaranteed to be dry. The silver lining is that desert rain passes quickly, and afternoon windows regularly open up even after a grey morning. Dress in layers you can actually peel off — a 53°F high feels different at noon than the 35°F you started in at dawn.
With a 35°F morning low, book tee times no earlier than 10 AM so the desert floor has had time to warm toward that 53°F high. Midday slots on weekdays are least crowded and catch the best light before the short December sun angle drops the temperature again after 3 PM.

Coming out of November, you lose 10°F on the average high (63°F down to 53°F) and pick up two more precipitation days, so December is noticeably colder and marginally wetter than the month before. Peak wind actually eases slightly, dropping 0.7 mph from November's 7.1 mph. Looking ahead, January brings no temperature relief — the high stays at 53°F — but adds another two precipitation days, making December the drier and calmer of the two cold months.
