Climate & Weather

Charleston sits in that sweet spot of the American Southeast where the climate feels almost indulgent for much of the year — but it also has a few sharp edges.


Spring (March–May) is arguably Charleston's finest season. Temperatures climb from the mid-50s into the low 80s, the azaleas and wisteria explode into color, and the humidity hasn't yet become oppressive. It's the kind of weather that makes people want to move there.

Summer (June–September) is a full-contact experience. Heat and humidity arrive together like old friends who don't know when to leave. Daily highs routinely sit in the low-to-mid 90s, but the feels-like temperature often pushes past 100°F. Afternoon thunderstorms pop up almost every day — brief, violent, and then gone — providing almost no actual relief. Hurricane season (June–November, peaking August–October) is a real consideration, and the low-lying geography means flooding is a recurring issue in certain areas of town even from heavy rain, not just named storms.

Fall (October–November) is awesome. The humidity finally loosens its grip, temperatures settle into the 60s and 70s, and the light turns that golden late-afternoon quality. Many locals consider October the best month of the year. Hurricane risk lingers into October, though.

Winter (December–February) is mild but can surprise you. Most days are in the 50s and 60s, rarely dipping below freezing. Snow is a genuine novelty — maybe once every few years — but when it does happen, the city essentially shuts down. Winter storms ocassionally bring ice, which is arguably more disruptive than snow.

The overarching theme of Charleston's climate is moisture — the Atlantic, the marshes, the tidal rivers, and the estuaries all conspire to keep the air heavy. Even on a "dry" day, there's a softness to the air that visitors from drier climates notice immediately. It's a city that smells of salt and pluff mud (especially close to the coast), and the weather is very much part of that identity.

Retiring in Charleston

Retiring in Charleston involves balancing the city’s historic charm with modern logistics like tax benefits and healthcare access. For 2026, South Carolina remains one of the most tax-friendly states for seniors, though the Charleston "Lowcountry" has a higher cost of living than the state average.

  • Financial & Tax Information 

    • South Carolina offers several specific financial perks for retirees that can significantly stretch a fixed income. The SC Department of Revenue (SCDOR) is the official source for the Homestead Exemption, which exempts the first $50,000 of your primary residence's assessed value from local property taxes for residents 65+.

       
      SmartAsset & Tax Foundation's key 2026 highlights include:

      Social Security: Fully exempt from state income tax.
      Retirement Income Deduction: Seniors 65+ can deduct up to $10,000 of retirement income (IRAs, 401ks, pensions)
      Income Tax: South Carolina has a graduated individual income tax with rates ranging from 0% to 6.0% for the 2025 tax year. 
      OBBBA (Federal): Note that under the 2025 "One Big Beautiful Bill," many retirees now qualify for an additional $6,000–$12,000 federal senior deduction, making Social Security tax-free for most middle-income households this year.
  • Healthcare Quality and Access

    • Charleston is a regional medical hub, which is a major draw for retirees.
