Coastal flooding has become a pressing issue in Charleston, South Carolina, driven by rising sea levels and an increase in tidal events.

Recent data from the National Weather Service reveals that 73% of recorded tides exceeding eight feet have occurred since 2015, highlighting a significant trend in flooding risks.

South Carolina ranks third among 41 coastal states for increased coastal flood events, experiencing an astonishing 580.3% rise since the study began.

The frequency of minor coastal flooding events has tripled in the past decade compared to the previous ten years, a change largely attributed to sea level rise.

Following moderate flooding on April 27, 2025, coastal flooding advisories were issued for parts of Charleston County.

Blair Halloway, Lead Forecaster for the National Weather Service Charleston, warns that flooding is expected to worsen in the future.

Ocean water intrusion poses a significant threat to homes, leading to costly repairs from issues such as rotted materials and mold.

Rob Bhatt, an Insurance Analyst, stresses the importance of flood insurance and recommends protective measures like elevating HVAC systems and installing flood vents.
