Of course there’s no time quite like summertime on Kiawah Island—but don’t count the other months out! Kiawah Island weather varies from season to season, but with our subtropical climate, you can enjoy the outdoors almost all year long. Our Kiawah Island weather report will clue you in on the best time to book for your perfect vacation. Whether you’re planning to relax on our pristine 10-mile beach or venture to downtown Charleston, find out which season is ideal for your visit.
Spring
There’s nothing quite like catching the fragrance of flowers in bloom as you whizz down Kiawah’s wooded bike trails.
Spring here is idyllic—kids are still in school so the island is a bit quieter, the temperatures hover between high 60s and low 80s, and in May, the ocean’s already warm enough to take a dip. Plus, downtown Charleston is oh-so-scenic with spring blooms, and the pleasant weather means you can comfortably spend whole afternoons wandering its cobblestone streets.
Ever-popular Easter is a mixed bag when it comes to weather. Many years, it’s sunny and wonderful. Others, the weather is still a bit crisp. But even if the temperature dips, the show goes on. Egg hunts and recreation events will keep you entertained if it’s too chilly for a day on the beach.
Summer
A hands-down favorite among vacationers and locals alike, summertime will show you Kiawah Island in full swing. With daily temperatures averaging upper 70s to lower 90s, it’s the perfect time to hit the beach.
On a rare few days of the season when the breezes are still, no-see-ums come out to pester beachgoers. And on a handful of others when the winds are high, blowing sand makes the beach a no-go. But the overwhelming majority of summer days are just plain perfect for kicking back and catching some rays or playing in the surf.
If you’re visiting in the summer, we recommend keeping your daytime adventures on the island, where the cool coastal breezes make temperatures manageable. Steer clear of downtown Charleston until the evening. All that summer sunshine can cause some real city scorchers.
Fall
Summer temperatures without the crowds—September is a gorgeous time to stay on Kiawah. As the fall marches on, daily highs begin to dip from the 80s to the 70s and 60s, so late fall is better for those who’d rather enjoy cooler days.
We’d be remiss if we didn’t clue you in on this important Kiawah Island weather fact: mid-September to mid-October is our storm season. While these months are lovely if the rain stays away, we always advise guests booking fall getaways to purchase travel insurance.
Winter
Winter brings chilly winds to our breezy beach town. When it comes to Kiawah Island weather in winter, average highs hover in the low 60s while lows dip to the low 40s and below; snow is uncommon but not unheard of.
If you’re planning on visiting the island during winter, bundle up and prepare for a low-key, low-traffic environment. The chillier months also tend to be the louder ones: most renovation projects begin then, so you may encounter some construction noise during your stay.
But chilly weather and construction aside, the season has its perks. Stay during the winter and you’ll feel like you have the whole island to yourself. Plan a trip around the holidays to enjoy The Sanctuary’s Christmas displays and the New Year’s fireworks.
Plus, once the weather starts cooling off in November, we offer 25% discounts for stays of four weeks or more, and guests who stay 91 days or longer don’t pay accommodation tax.
