August in Charleston forces you to manage the scorecard before you even reach the first tee. The average high of 86°F combined with a low of 76°F means the daily temperature swing is only 10°F — there is no cool part of the day to hide in. That narrow window keeps humidity locked in from early morning through dusk, which slows greens slightly from their spring pace and makes approach shots that normally stop spin out and release. Factor in longer par-4s playing firmer but approaches landing softer, and your expected scoring shape for the round shifts before you've hit a ball.
The 25 precipitation days make August the wettest month of the year in Charleston, and those aren't all gentle afternoon drizzles. Afternoon thunderstorms can suspend play, and with 25 days of precipitation across 31 days the odds of a delay on any given outing are significant — which means a 7 AM tee time isn't just about beating the heat, it's about finishing before the sky shuts the course down. The one statistical silver lining: peak wind averages 11.6 mph, the calmest reading of any month. On holes where wind typically costs you a club or two, August gives you a rare chance to hit stock yardages.
Book the earliest available tee time — ideally at or before 7 AM — since afternoon thunderstorms arrive with little warning and 25 precipitation days across the month means the odds of a mid-round suspension on any given afternoon are real. Weekend slots before 8 AM fill quickly in August because locals already know this, so lock in your time at least two weeks out. See how conditions rate hour by hour on our playability scale.
July runs 2°F hotter and logs 2 fewer precipitation days than August, meaning August is actually slightly cooler but meaningfully wetter — 2 additional rain days offset any marginal relief from the temperature drop. September drops the average high another 3°F to 83°F and sheds 7 precipitation days, making it a noticeably more playable month for anyone who can wait. Peak wind ticks up slightly into September at 12.8 mph versus August's 11.6 mph, but that modest increase is a small price for far fewer rain delays.

August averages a high of 86°F with a low of 76°F and logs 25 precipitation days — the wettest month of the year — so conditions are genuinely challenging. That said, peak wind is only 11.6 mph, the calmest of any month, which helps on exposed coastal holes. Early tee times let you get 14–15 holes in before the typical afternoon storm window opens.
With 25 precipitation days in August, precipitation falls on most days of the month, and a significant portion of that comes as afternoon thunderstorms that build quickly along the coast. Most courses will issue a horn and clear the course when lightning is within the area, so rounds starting after noon carry a real risk of suspension. Booking a dawn patrol tee time is the most reliable way to complete a full 18.
