TLDR: Does it Snow in Charleston? In short – rarely. Charleston’s climate is classified as humid subtropical, which means hot, sultry summers and mild winters. As a coastal Southern city, Charleston averages virtually 0 inches of snow per year. Typically, winter temperatures stay well above freezing, so snowfall is an extreme rarity. You might see a brief flurry once in a blue moon (the chance of a few snow flurries usually comes only in late December or early January), but accumulation that sticks is almost unheard of. Most Charlestonians will tell you they can go many years without seeing a single snowflake. Charleston’s rare snowfall events – like the surprise January 2018 snowstorm pictured above – are memorable precisely because they happen so infrequently. In that storm, Charleston saw about 5 inches of snow, nearly breaking the city’s historical record. Such events are exceptional; when snow does fall, it’s a fleeting novelty that melts quickly in the Lowcountry sun. Winters here are short and mild, with daytime highs often near 60°F (16°C) and nights around 40°F (4°C), making Charleston a welcome escape from places with true winter weather. So if you’re staying at The Iris Hotel in winter, you likely won’t need a shovel – just a light jacket and maybe an umbrella for the occasional rain shower. Winter in Charleston: Mild Days & Cozy Nights Charleston’s winters are typically mild and comfortable. Average highs hover in the upper 50s°F to low 60s°F (around 15°C), and overnight lows rarely dip below freezing. Snow is practically nonexistent, so you can leave the heavy parka at home. Instead, expect cool, crisp mornings, some pleasantly sunny afternoons, and periodic rainy days. (Charleston sees about 3 inches of rainfall per winter month on average.) Humidity is low and there’s still plenty of sunshine between those winter showers – remember, Charleston actually gets more sunny days than the U.S. average in a year. Even without snow, Charleston radiates seasonal charm in winter. The downtown historic district dresses up for the holidays: you’ll see wreaths on antebellum homes and twinkling lights on King Street. Festive events abound, from holiday markets and parades to light displays. (One beloved tradition is the Holiday Festival of Lights, a massive light show running from mid-November through December at James Island County Park.) In December, you can catch holiday boat parades in the harbor or performances of “A Christmas Carol” at local theaters. By January and February, the city quiets down – a perk for travelers seeking fewer crowds and great hotel deals (these months tend to have the lowest room rates of the year in Charleston). Tips for Winter: Pack layers and a medium-weight coat or sweater for the cooler evenings, but you’ll often be comfortable in just a light jacket during the day. Since winter is Charleston’s “off-season,” take advantage of the calm: it’s easy to stroll museums, dine at popular restaurants without long waits, and enjoy uncrowded views of attractions. Guests at The Iris Hotel will love coming back to a cozy, well-heated suite after exploring – perhaps curling up with a warm drink knowing that tomorrow’s forecast is likely sunny and mild. And if a rare snowflake does fall, consider it a bonus story to tell! Spring in Charleston: Blooming Beauty & Outdoor Fun Spring is Charleston at its most spectacular. From early March into early June, the city comes alive with vibrant blooms – azaleas, dogwoods, jasmine, and wisteria drape the city in color. Daytime temperatures climb into the pleasant 70s°F (21–26°C) by April and May, with cool nights in the 50s°F (10–15°C). It’s warm enough to enjoy the outdoors comfortably, but not yet the humid heat of summer. Rainfall is relatively modest in spring (around 3–4 inches per month) and you’ll mostly encounter clear skies – though an occasional shower can pass through, so it’s wise to have an umbrella handy. Charleston’s spring calendar is packed with events and festivals. This is peak season for visitors, and for good reason. March kicks off with the world-class Charleston Wine + Food Festival, and as spring unfolds you’ll find cultural events at every turn. Historic downtown becomes a playground for house and garden tours, like the annual Festival of Houses & Gardens, where you can peek into ornate private homes and flowering courtyards. Runners converge for the famous Cooper River Bridge Run in early April. And in late spring, the city hosts Spoleto Festival USA, one of the nation’s biggest performing arts festivals, filling Charleston with opera, jazz, theater, and more. (If you plan to attend these popular events, be sure to book The Iris well in advance – spring is high season and hotels fill up.) With the gorgeous weather, spring is the perfect time to explore on foot or by bike. The Iris Hotel’s central location means you can step outside and wander Charleston’s cobblestone streets or even rent a bicycle to cruise around. (In fact, spring weather in Charleston is ideal for biking around the historic districts.) Enjoy a breezy walk along the Battery waterfront, picnic under the blooming magnolias in White Point Garden, or hop over to Folly Beach on a warm April afternoon – it might be just a bit early for a swim, but the sands are lovely for a stroll. Tips for Spring: Dress in light layers. Early spring can bring chilly mornings, but by afternoon you’ll be comfortable in short sleeves. A light sweater or cardigan plus a rain jacket (just in case) should cover all bases. Don’t forget comfortable walking shoes – you’ll want to roam everywhere to soak in the sights and scents of Charleston in bloom. Spring is a prime time to visit Charleston, so expect more fellow travelers out and about. Fortunately, as a guest of The Iris, you’re staying steps away from attractions (no need to find parking during busy festival days!). After a day of garden tours and gallery hopping, you can relax in your stylish suite at The Iris, perhaps planning which award-winning restaurant to walk to for dinner in the pleasant evening air. Summer in Charleston: Sun, Heat, and Coastal Breezes Summer in Charleston means heat, humidity, and a whole lot of sunshine. From June through August, afternoon highs typically reach the upper 80s to low 90s°F (31–33°C) and the humidity often hovers between 70–80% – it’s the kind of sultry Southern summer you read about. It’s not unusual to have stretches of days in the 90s°F, and pop-up thunderstorms are a common late-day occurrence that offer dramatic downpours and then clear out. (In fact, summer is the wettest time of year – August alone averages about 7 inches of rain, usually in quick bursts.) The good news is those storms provide relief and are often followed by cooling coastal breezes. Even on the hottest days, a trip to the water or a shady veranda with a cold sweet tea can make everything right. Summer is beach season in Charleston. Locals and visitors alike flock to nearby beaches: Folly Beach, Sullivan’s Island, and Isle of Palms are all within a 20–30 minute drive from downtown. The Iris Hotel puts you close to the action – you can spend a day riding the waves at Folly or paddleboarding in the marshes, then be back to your suite for a refreshing shower before dinner. Charleston’s waterways also offer plenty of ways to cool off; whether it’s a harbor cruise, kayaking tour, or even just a ferry ride to Fort Sumter, being on the water is a favorite summer pastime (after all, this city is surrounded by rivers and ocean). If you prefer to stay in town, summer is a great time to enjoy Charleston’s museums, galleries, and shops during the steamy midday hours, then venture out in the cooler mornings and evenings. You’ll find that downtown is a bit quieter in summer than in spring – many travelers visit in spring or fall for sightseeing, so summer in the city feels slightly more relaxed (aside from the bustling weekend nights on King Street!). This makes it a surprisingly nice time to explore landmarks like the Charleston City Market or Rainbow Row with fewer crowds, as long as you don’t mind the heat. Tips for Summer: Pack for hot weather. Lightweight, breathable clothing (shorts, sundresses, linen and cotton fabrics) and sun protection are musts. Bring sunscreen, a wide-brimmed hat, and sunglasses – Charleston’s UV index can be high in summer. Also throw in a portable umbrella or rain jacket for those sudden afternoon thunderstorms. Many indoor venues blast the air-conditioning, so having a light sweater for restaurants or museums can be handy. Stay hydrated – carry water if you’re walking around in the heat. If you’re sensitive to humidity, plan outdoor activities for morning or late day, and use mid-afternoon to enjoy The Iris’s air-conditioned comfort. One of the perks of staying at The Iris is returning to a cool, luxurious suite after a day in the sun – the perfect respite before heading back out for a sunset dinner or rooftop cocktail when the evening breezes set in. And a note on the calendar: hurricane season runs from June through November in this region, peaking in late summer. Major storms are infrequent, but it’s wise to keep an eye on forecasts if you’re visiting during August or September. Travel insurance that covers weather isn’t a bad idea in the unlikely event a storm disrupts plans. Most likely, though, your summer stay will just feature classic Charleston heat and hospitality. Fall in Charleston: Crisp Air & Colorful Events When autumn arrives, Charleston enjoys a welcome breath of cooler air – but not too cool. Fall is a favorite time for many visitors because the weather hits that sweet spot of warm-but-not-hot. September can still feel summer-like (average highs in the mid 80s°F, 29°C) and remains somewhat humid, with a chance of rain especially early in the fall (September sees about 6 inches of rain on average, often due to lingering tropical weather). By October, however, the humidity drops and the days become brilliantly clear. October highs are in the mid to upper 70s°F (25°C), with nights in the comfortable 50s°F (10–15°C) – perfect for evening strolls. November brings true sweater weather: highs around 70°F (21°C) and crisp nights around 50°F (10°C). Rainfall also tapers off significantly by late fall – November is actually one of the driest months of the year in Charleston. The result: autumn days with bright sunshine, clear blue skies, golden marshes, and cool, dry breezes – an absolutely gorgeous atmosphere for exploring the city. Fall is also a season of festivities and a return to leisure after the hot summer. As the weather moderates, Charleston’s event scene ramps up again. In September, you might catch the tail end of restaurant week or an outdoor concert series. October is packed with fun: there are harvest festivals, pumpkin patches, and the popular MOJA Arts Festival celebrating African-American and Caribbean arts. Historic sites offer spooky ghost tours leading up to Halloween (what better way to spend an October evening in America’s most haunted historic city?). Also in October, the Preservation Society hosts Fall Tours of Charleston’s finest homes and gardens, giving you another chance (after spring) to peek into the city’s elegant private residences – now framed by autumn decor and fall flowers. By November, the holiday season begins to stir: you’ll see holiday markets and decorations appear before month’s end. Through all these months, the city’s outdoor dining and rooftop bars are in full swing, taking advantage of the pleasant temperatures. This season often sees thinner crowds than the spring rush, so you can meander the French Quarter or Folly Beach with a bit more elbow room. It’s an ideal time for a carriage ride through downtown or a boat tour of the harbor – you won’t be wilting in the heat, nor will you need a heavy coat. Tips for Fall: Layer up with lightweight long sleeves, and have a light jacket or sweater for the cooler mornings and nights. Early fall (September) can still feel summery, so pack a mix of short sleeves and a pair of shorts along with your jeans or slacks. By late October, you’ll appreciate having a jacket or cozy sweater in the evenings. Comfortable footwear is essential year-round, but especially in fall when the weather is ideal for walking tours (you might cover a lot of ground exploring Charleston’s nooks and crannies!). Keep an eye on the forecast during hurricane season’s tail end in early fall, but by mid-October that worry fades. Fall is arguably the best time for a balanced Charleston experience – warm days, cool nights, lots of events, and natural beauty. And whatever autumn itinerary you choose, The Iris Hotel’s prime location means you’re never far from the action or the comfort of your suite when you’re ready to relax. Step out of The Iris into a crisp October morning to grab coffee at a local café, or unwind on your suite’s balcony (if your room has one) on a pleasant November afternoon – the fall weather invites you to savor every moment.
