St. Simons Island is home turf for dozens of PGA Tour pros, with marsh-and-oak golf moderated by the Atlantic. Spring and late fall are the prime windows — the RSM Classic plays here in November for a reason. Summer sea breezes help, but humidity and storm chances still favor morning rounds.
Precipitation days cluster unevenly across St. Simons Island's calendar, and that clustering determines whether fairways are firm or saturated. December logs only 8 precipitation days — the lowest of any month — while August piles up 27, meaning fairways on this sandy-marsh terrain can stay saturated for weeks on end during late summer. The gap between those two extremes is enormous, and it shapes everything from course conditioning to tee-time strategy.
The island's Atlantic-edge location keeps temperatures moderate year-round, with highs ranging from 63°F in January to 89°F in July. But temperature alone doesn't tell the story here. It's the clustering of rain days — 21 in June, 26 in July, 27 in August — that pushes serious golfers toward the calendar's drier edges, where fairways have time to drain and ball roll is actually predictable.
March through April sees 11–12 precip days per month, similar to winter but with rising temperatures pushing into the low-to-mid 70s. The real catch is wind: April's average peak of 14.9 mph is the highest of any month, routinely affecting club selection on exposed coastal holes. May turns notably wetter at 17 precip days, signaling the start of the island's rainy season.
July and August average 26 and 27 precipitation days respectively — that's nearly every other day seeing measurable rain. Highs reach 87–89°F, and while July's day-to-night swing is 13°F, August and September narrow to just 11°F, leaving almost no overnight drying window before the next storm. Morning rounds before the daily convective storms are the practical move, and even then expect soft, slow conditions.
October is a turning point: precip days fall sharply to 11, temperatures ease to a 77°F high and 64°F low, and peak winds drop to 12.8 mph — among the calmest readings of the year. Fairways that were waterlogged through August and September get several weeks to drain and firm. November holds at 13 precip days with highs of 70°F, which is exactly the window the RSM Classic targets.
December delivers the island's fewest precip days at 8, and while highs sit at just 64°F, that's still within comfortable range for players who dress in layers. January and February average 10–11 precip days, keeping conditions reasonably dry even if morning lows dip to 47–51°F. Wind runs 13.5–13.7 mph in those months, so calm days are worth grabbing when they appear.
October and November each see only 11 and 13 precip days respectively, allowing fairways meaningful recovery time after the summer deluge. October's avg high of 77°F and low of 64°F sits squarely in the 60–80°F ideal range, and peak winds of 12.8 mph are the lightest fall reading of any month in that season. December drops to just 8 rain days — the annual minimum — with a 64°F high that still allows comfortable play for golfers who layer up.
October and December are your best bets. October sees only 11 precip days after the summer saturation period, giving courses several weeks to drain and firm up. December drops even further to 8 precip days — the driest month of the year — so fairways tend to be at their most consistent for ball roll and distance.
It's playable, but the numbers argue for early mornings only. July and August average 26–27 precipitation days, with daily convective storms typically building by early afternoon. Temperatures hit 87–89°F with lows staying in the mid-70s, so there's little overnight drying. Book the first tee time available and plan to be off the course by midday.
Peak winds average 11.9–14.9 mph across the year, so calm days here are the exception rather than the rule. April is the windiest month at an average peak of 14.9 mph, followed closely by March at 14.3 mph. July is the calmest at 11.9 mph, though the trade-off is the wet, humid conditions that come with it.
