Risk Overview

About Natural Disaster Risk in Brevard County, Florida

Brevard faces severe, broad-spectrum risk

Brevard County's composite risk score of 98.41 ranks in the "Relatively High" category, placing it among America's highest-risk counties. This Space Coast location faces extreme exposure to hurricanes, flooding, and wildfire simultaneously.

Second-riskiest county in Florida

Brevard's 98.41 score exceeds Florida's 75.74 average by a dramatic margin, ranking it second only to Broward County (99.46). The county's long Atlantic coastline and dense urban population concentrate natural disaster exposure at exceptional levels.

Most extreme risk in its region

Brevard County (98.41) dwarfs the risk profiles of inland neighbors like Volusia (scores unavailable) and significantly exceeds most surrounding counties. Only its neighbor Broward approaches Brevard's extreme vulnerability to multiple hazard types.

Hurricanes lead, followed by wildfire and tornado

Hurricane risk peaks at 99.71—among the nation's highest—while wildfire (97.17) and tornado risk (95.29) round out a triple threat. Brevard residents face compounded exposure to all major wind and fire hazards across the calendar year.

Multilayered insurance is not optional

Brevard County residents must obtain homeowners insurance with maximum hurricane wind coverage and separate flood insurance—both are critical. Consider reinforcing your home's roof, garage doors, and windows, and maintain evacuation plans for hurricane season (June–November).

Risk Verdict

Brevard County's composite risk score ranks at the 98th percentile nationally, reflecting genuine multi-hazard exposure for residents. At this risk level, having a documented household preparedness plan — not just awareness — is the meaningful next step for Brevard County residents.

Hazard Breakdown

Hurricane risk is Brevard County's dominant natural hazard, ranked at the 100th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 97th percentile nationally. Additional tracked hazards include tornado (95th percentile), flood (95th percentile), earthquake (46th percentile).

Preparedness Context

With hurricane ranked at the 100th percentile nationally, Brevard County sits in a zone where multi-day supply readiness matters: grid outages after landfalling storms can last one to three weeks in heavily affected areas. Wildfire, the county's second-ranked hazard at the 97th percentile nationally, represents an additional preparedness consideration for Brevard County independent of hurricane season. Insurance gaps are the most common post-hurricane financial shock: standard homeowners policies typically exclude flood damage and may have a separate wind deductible. Brevard County households benefit from a pre-season insurance review confirming both wind and flood coverage.

Regional Context

The Florida county average is 22.7 composite points below Brevard County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
