May in Charleston, SC: shoulder season for golf — playable with smart tee time selection. Best tee times: morning before noon for the most comfortable round.

May sits at a transition point in Charleston's golf calendar — warmer and wetter than April, but not yet the oppressive heat and storm frequency that defines June. The average high reaches 80F with lows at 67F, keeping most morning rounds genuinely comfortable before afternoon temperatures climb. At 14 precipitation days, it's the 4th-driest month of the year, which sounds counterintuitive given the region's reputation, but the numbers hold. Peak winds average 13.6 mph, placing May 5th on the annual windiness scale — present enough to matter on exposed lowcountry layouts, but slightly calmer than April's 14.6 mph.
The 13F daily swing between high and low means an early tee time feels meaningfully different from a midday one. Mornings in May are the sweet spot: temperatures in the high 60s, manageable wind, and most of the rain accumulating in scattered afternoon thunderstorms rather than sustained fronts. Plan your round accordingly and May delivers some of the most playable conditions Charleston offers all year.
Book the earliest available tee time — 6 or 7 AM starts let you finish before the heat pushes the high toward 80F and before afternoon convective storms develop, which account for the bulk of May's 14 precipitation days. Morning slots at popular area courses fill quickly in May, so reserving well in advance is worthwhile. See how conditions rate hour by hour on our playability scale.
May arrives 7F warmer than April and adds 3 more precipitation days, so expect slightly more humidity and a higher chance of an afternoon delay — but winds actually ease by 1 mph coming out of April. Moving into June, the gap widens considerably: temperatures climb another 5F to an 85F average high, while precipitation days jump by 6 to reach 20, making June noticeably stormier and more humid. May is effectively the last month before Charleston's summer weather pattern locks in.

Yes, but the window is narrow. The average high is 80F and lows hold at 67F, so mornings are comfortable, but midday rounds in late May can already feel warm and humid. With only 14 precipitation days, May is actually the 4th-driest month of the year, giving you a reasonable chance at a dry round if you tee off early.
Scattered afternoon storms are a real factor — nearly half of May's days see some measurable precipitation, spread across 14 days in the month. Most activity develops after noon as daytime heating kicks in, so morning tee times carry significantly lower risk. Keep an eye on radar once you reach the back nine if you've started late.
