December in St. Simons Island, GA: peak season for golf — great conditions and a wide playing window. Best tee times: late morning to early afternoon after dew burns off.
| Average December Weather | |
|---|---|
| Avg daily high | 64°F |
| Avg daily low | 49°F |
| Rainy days | 8 / mo |
| Avg peak wind | 12.4 mph |
December's defining variable on St. Simons Island is precipitation — or the lack of it. Eight rainy days makes this the driest month of the year, which means you're looking at more uninterrupted rounds than any other time on the calendar. Combine that with a 12.4 mph peak wind (third-calmest of the year) and conditions that rarely turn hostile, and December earns its Peak Season badge on the strength of reliability, not warmth.
The tradeoff is temperature. A 64F average high puts December second-coldest of the year, and the daily swing of 15F between morning and afternoon means the same round can feel like two different seasons. Tee off at 8 AM with a 49F chill and you'll be peeling layers by the back nine. Plan for that range and December golf in St. Simons Island plays better than the calendar date suggests.
Book morning tee times no later than 8–9 AM to take advantage of the low precipitation window, but layer up — 49F lows mean the first few holes will be cold until the day warms toward 64F. Because December is peak season, weekend slots fill faster than the weather might imply, so reserve at least a week out. See how conditions rate hour by hour on our playability scale.
December is a meaningful improvement over November in one key way: five fewer rainy days, dropping from 13 down to 8, even as temperatures cool by 6 degrees. Compared to January, December holds a slight edge — two fewer rainy days and winds that run about 1.1 mph calmer, while the average high is nearly identical at just one degree warmer. If you're choosing between the two shoulder months, December is the drier and slightly more settled option.

Yes — December is actually the driest month of the year here, averaging just 8 days with precipitation, which gives you strong odds of uninterrupted rounds. Winds average a peak of 12.4 mph, third-calmest of the year, so conditions are more cooperative than the winter date implies. The main adjustment is dressing for a 49F morning that climbs to around 64F by afternoon.
Lows average 49F, so early morning rounds will feel genuinely cold by coastal Georgia standards. Highs reach 64F, which sits just inside the comfortable range for golf, but the 15-degree daily swing means layering is essential rather than optional. Plan to start bundled and strip down by the middle of your round.
