Risk Overview
About Natural Disaster Risk in Glynn County, Georgia
Glynn County faces significant coastal risks
Glynn County's composite risk score of 83.68 substantially exceeds the national average, placing it in the "Relatively Moderate" risk category. This elevated exposure reflects the county's coastal location and vulnerability to multiple hurricane-driven hazards.
Well above Georgia's risk average
Glynn County's score of 83.68 towers over Georgia's state average of 39.49, positioning it among the state's higher-risk counties. This doubling of state-average risk underscores the unique hazard profile of Georgia's Atlantic coastline.
Riskiest county in coastal Georgia
Glynn County (83.68) faces notably higher composite risk than inland counties across central Georgia, reflecting its oceanside exposure and hurricane vulnerability. Its risk level matches or exceeds that of other major Georgia metropolitan areas, making coastal preparedness paramount.
Hurricanes and wildfires dominate threats
Hurricane risk in Glynn County reaches a critical 95.87, the highest of all hazard types and reflecting direct Atlantic exposure. Wildfire risk scores 92.11, while flood risk reaches 89.60, creating a triple threat particularly acute during Atlantic hurricane season.
Coastal insurance is absolutely essential
Glynn County residents must carry flood insurance through the National Flood Insurance Program or private carriers, as this coverage is mandatory for mortgaged properties in coastal zones. Additionally, ensure your homeowners policy includes wind and hail coverage, consider hurricane shutters or impact-resistant windows, and maintain evacuation plans updated annually.

Wildfire at the 92th percentile nationally is Glynn County's secondary hazard, often intensified by the same weather systems that produce hurricane conditions. For extended post-storm outages common in Glynn County's hurricane zone, a portable generator (operated outdoors only) and a supply of non-perishable food for at least seven days provides meaningful household resilience.
