What to Expect in South Carolina
The honest trade-offs. People who move here usually don't regret it, but these are the things to plan for.
Hurricane/flood risk is real in the Lowcountry — Katrina, Matthew, Florence, Ian all caused significant damage. "Sunny day flooding" in Charleston happens 3-5 times/year now (king tide + sea level rise), closing streets and roads with no storm.
Extreme summer heat and humidity — July-August regularly hit 92°F+ with 75%+ humidity, making outdoor activity miserable. Heat index routinely 100°F+. This is worse than Alabama due to coastal moisture.
Insurance costs are spiking coastal — homeowners insurance increased 15-25%+ annually in Charleston area. Flood insurance is separate and expensive. Some insurers are exiting the state entirely.
Charleston is over-touristed and gentrified — median home $680K+, rents $1,800+ for 1BR, neighborhoods transformed by Airbnb. Livability for locals has declined.
"Sunny day flooding" in Charleston is frequent and worsening — roads close 3-5 times/year on high tide days, no storm required. This is a harbinger of future coastal uninhabitability.
