Charleston's colorful historic homes and cobblestone streets, world-class museums, and nearby beaches make it a popular destination. And while the weather is moderate year-round, the best times to visit Charleston are from March to May and from September to November. In the spring, the flowers are in full bloom, the heat and humidity haven't set in, and hurricane season hasn't begun. Come fall, there are fewer crowds, cheaper hotel rooms, and ideal temperatures.
Whenever you decide to make your journey, use this guide to plan your next trip.
The Weather in Charleston
Located on the South Carolina coast, Charleston has a subtropical climate, which makes temperatures and conditions favorable almost all year. In winter, highs are in the mid-50s and rarely dip below freezing, even at night. Summers can be hot and humid, with temperatures soaring into the upper 80s and low 90s—especially in the city proper. This is a good time to take advantage of nearby beaches, but you'll want to pack an umbrella: August is the city's wettest month. Spring and fall offer the most favorable weather, with temperatures in the 60s and 70s, sparse humidity, and little rain.
Peak Season in Charleston
There are two peak seasons in Charleston. The first is in spring, from March to May. This is when the magnolia trees and azaleas are in full bloom, the temperatures are mild, and annual events like the Charleston Food & Wine Festival and Spoleto Festival USA are in full swing. The city is a particularly popular destination during the Easter holidays and spring break, so expect hotel rates to soar and attractions to be crowded.
The second peak comes in the fall (between September and November), when the temperatures cool off, the humidity is less stifling, and the city is ideal for walking and exploring.
Hurricane Season in Charleston
Because of its location on the Eastern seaboard, the city is at risk for hurricanes. Hurricane season is from June 1 to November 30 annually, with peak time between August and October. However, South Carolina has a lower risk of hurricanes than Florida or other states on the Atlantic and Gulf Coasts. On average, only 11 percent of all hurricanes making landfall since 1851 have hit South Carolina; only six of them were Category 3 or higher.
While odds are unlikely you'll encounter a hurricane during your trip, most hotels and airlines will refund or rebook your trip if you do. You can also purchase hurricane insurance as an extra precaution.
Winter in Charleston
Winter is off-season in Charleston, with crowds dissipating after the holidays and remaining sparse through early spring. Expect cheaper hotel rates, fewer tourists, and relatively mild temperatures, with highs in the upper 50s and lower 60s and lows in the mid 40s. If you plan to do a lot of walking, layer and pack a warm jacket: It can get quite breezy and chilly, especially by the waterfront.

Summer in Charleston
Summers can be oppressively hot and humid in Charleston, but air conditioning is plentiful, and the nearby beaches offer some respite from the weather. You'll still find larger crowds through the 4th of July holiday, but in general, the city is less crowded and rates are lower during this time of year. Pack rain gear for August as it's the city's wettest month.
