Kiawah Island Ocean Course Weather by Month & Best Time to Play

Loading course forecast…

Kiawah is a year-round course, so the question isn't whether it's open but which trade-off you want. Spring and fall bring the most comfortable air and the biggest crowds. Summer brings heat, afternoon storms and a different set of cart rules. Winter is mild and quiet but has cool mornings. The resort itself says spring and fall are the most popular times, and its busiest periods are mid-March to mid-May and mid-September to Thanksgiving.

Values come from ERA5 model hours requested at our audited Ocean Course point, converted to Eastern time with daylight saving applied, 2021–2025. They show how often conditions happened, not a forecast for your day.

Walking, carts and caddies

The resort's caddie page says the Ocean Course is walking only, except in June, July and August, when carts are allowed for golfers teeing off after 10am. Those carts stay on the paths, and anyone using one in summer must take a forecaddie. Caddies aren't mandatory for walkers but are highly recommended. There's no caddie fee; the resort recommends a service-based gratuity of $120 per player for a walking caddie and $60 per player for a forecaddie. Pull carts are allowed, but the resort doesn't rent them.

In summer, that sets up a real choice. Walk from an early tee time: in July the heat index was below 90°F on most days at 7–9am, though it usually passed 90°F by late morning while you'd still be out on the course. Or ride after 10am, when it was already at 90°F or more on 54% of July days at 10am and storms become more likely as the afternoon goes on.

Booking, cancellations and rain

The Ocean Course is open to the public; you don't need to stay at the resort, though resort guests get discounts. Guests with a confirmed stay can book tee times at any point for the length of their visit; non-guests can book no more than 60 days ahead. Groups of fewer than 12 can cancel 48 hours in advance without penalty. If weather stops your round, the resort issues a prorated, hole-by-hole refund on a resort gift card: complete 6 holes and you get two-thirds of the round's cost back as credit. The official pages we checked don't list a green fee. Allow about an hour from Charleston International Airport, plus another 20 minutes to reach the Ocean Course. Confirm terms on the official golf FAQ (checked 2026-11-10).

The Atlantic hurricane season officially runs from June 1 to November 30, which covers summer and the busy fall weeks. Our five-year averages don't single out tropical storms, so watch the National Hurricane Center in the days before a trip and read your travel insurance terms.

Five-year averages for 2021–2025 from ERA5 reanalysis, requested at our audited Ocean Course point. ERA5 is a coarse regional model, and the grid point used is 32.75°N, 80°W, about 16 km north of the course near Charleston. That cell mixes land, marsh and harbor water, so it probably understates wind on the exposed oceanfront holes. Treat these as a regional guide, not on-course measurements or 30-year normals.

Wet days are the average number of days per month with at least 1 mm of precipitation, not your chance of rain on a given day. Reanalysis models tend to spread summer showers across more days than a single rain gauge records, so compare months with each other rather than reading the summer counts literally. Wind is the mean speed at 10 m during daytime hours, not gusts.

The resort describes the Ocean Course as having ten holes along the Atlantic and the other eight running parallel to them. Pete Dye raised the course so every hole had an ocean view, which also left it open to the wind. According to the resort, there's no prevailing wind direction, so the course was effectively designed to play two ways, for easterly and westerly winds, and the same hole can play up to eight clubs different from one round to the next. We haven't measured that; our regional wind data can't tell you how any single hole plays, so we don't label holes as into or down the wind. For your round, check the hourly wind direction and gusts in the live forecast above, then use our golf wind calculator for a rough plays-like yardage.

The one tournament week we have is the 2021 PGA Championship. At players' tee times in rounds 1 and 2, it averaged 12.8 mph of wind with gusts around 26.7 mph, which ranks it number 5 of 39 one-off tournament weeks in our windiest PGA Tour courses guide. That's one week from a different weather record than the table above, so it isn't the course's normal climate.

Across regular Tour events, our wind and tee-time wave study found the windier wave averaged about 0.93 extra strokes per player for each 10 km/h of extra wind. That's a Tour-wide pattern for professionals at other courses, not a Kiawah or amateur score forecast.
