September sits at the hinge between Aiken's punishing summer heat and its comfortable fall stretch. Coming out of August — the rainiest month in recent data at 20 precip days — September cuts that figure nearly in half to 12, making it the 5th-driest month of the year. The high drops 6°F from August's 89°F down to 83°F, and while that still qualifies as warm, mornings starting around 66°F mean the first two hours on the course feel genuinely pleasant.
The month is best understood as a transition, not yet fall but meaningfully different from summer. Winds hold at 10.5 mph — the 4th-calmest ranking of the year — so wind management isn't a primary concern. Expect some afternoon heat and the occasional thunderstorm, but the window for comfortable rounds is noticeably wider than anything August offered.
With afternoon highs still reaching 83°F and scattered storms possible, booking a 7–8 AM tee time gets you through most of the round before the heat builds. Unlike August, the reduced rain-day count means you're less likely to see that early slot disrupted, so committing earlier in the week rather than waiting for a last-minute opening makes sense. See how conditions rate hour by hour on our playability scale.
September represents a sharp break from August: eight fewer rain days and a 6°F drop in the average high make a real on-course difference, even if the afternoons still feel warm. The move into October is quieter but meaningful — five fewer precip days and another 8°F shed from the high, landing at 75°F, which is closer to the site's ideal 60–80°F range. Wind stays essentially flat across all three months, shifting less than 1 mph in either direction.

At an average high of 83°F, September afternoons can feel warm, especially with lingering late-summer humidity. Morning tee times in the 66°F range are quite manageable, though, and the month ranks 4th-hottest of the year — not at the peak. If you've played Aiken in July or August, September will feel like a noticeable improvement.
September averages 12 precipitation days, which is nearly half the 20 days recorded in August and qualifies it as the 5th-driest month of the year. Afternoon pop-up storms are still possible, but the frequency drops sharply enough that planning a multi-day golf trip in September carries considerably less weather risk than the same trip in August.
