Most golfers expect September in Myrtle Beach to feel like a meaningful break from summer — cooler, drier, easier to walk 18. The reality is more complicated. At 82°F average high and 70°F overnight low, the heat and humidity still weigh on afternoon rounds, and with 17 precipitation days September ranks as the 3rd-wettest month of the year. That's not the autumn reprieve many anticipate.
The actual surprise cuts the other way, though: those 17 precip days tend to be brief afternoon thunderstorms rather than all-day washouts, and peak wind sits at just 11 mph — 4th-calmest of any month. Early tee times regularly deliver manageable conditions before the heat and storm potential build. Golf in Myrtle Beach in September rewards golfers who plan around the clock, not around the calendar.
Book the earliest available tee time — the 6–8 AM window consistently escapes both peak heat near 82°F and the afternoon convective storms that account for much of the month's 17 wet days. Last-minute deals are common mid-week as golfers cancel on uncertain forecasts, so checking availability 24–48 hours out can yield better rates without meaningful added risk. See how conditions rate hour by hour on our playability scale.
September drops 3°F off August's 85°F average high and sheds a significant 8 rain days — a real improvement in storm frequency even if temperatures still feel firmly summery. The bigger transition comes one month later: October cuts another 7°F, falls to just 9 precipitation days, and the daily temperature swing widens considerably, making it the cleaner fall window most September visitors were actually hoping for. If you can only choose one, October delivers the comfortable round September promises but rarely provides.

It depends on your expectations. Temperatures average 82°F at the high and 70°F at the low, so it still feels like summer, and September is actually the 3rd-wettest month of the year with 17 precipitation days. That said, peak wind is only 11 mph and early morning rounds can be genuinely pleasant before heat and storms build — it's workable, but not the fall deal some visitors assume it is.
They're frequent but usually short-lived — the 17 precipitation days largely reflect quick convective storms that form in afternoon heat rather than prolonged rain events. Teeing off before 8 AM sidesteps most of them, since storm activity typically peaks mid-to-late afternoon. Keeping an eye on a radar app during your round is worthwhile throughout the month.
