Relative to other U.S. communities, Semmes's natural disaster risk is well above the U.S. national average of 4.5/10, considerably above the 6.0/10 state average. The hazard distribution here is led by hurricane and coastal flood, as measured by FEMA across Mobile County.

Given Semmes's very high risk classification, residents should treat disaster preparedness as a year-round priority. This means maintaining updated homeowners and flood insurance, building a 72-hour emergency kit, knowing the evacuation routes for the primary hazards, and signing up for local emergency alert systems.
