Risk Overview
About Natural Disaster Risk in Aransas County, Texas
Aransas faces moderate national risk
Aransas County scores 61.20 on the composite risk scale, placing it in the relatively low category but above the national average. This Gulf Coast location's risk profile reflects its coastal exposure to tropical hazards.
Above average for Texas
Aransas County's 61.20 composite score exceeds Texas's state average of 49.00, reflecting higher-than-typical natural disaster exposure for Texas communities. The county ranks among the state's more hazard-exposed regions.
Similar coastal risk pattern
Aransas County's 61.20 score reflects typical coastal Texas exposure, placing it near other Gulf-facing communities in the state's mid-range for composite risk. Neighboring coastal areas share comparable hurricane and flood vulnerabilities.
Hurricanes dominate coastal threats
Hurricane risk reaches 91.24 in Aransas County—exceptionally high and the dominant hazard for this Gulf Coast location. Flood risk (67.80) and wildfire risk (61.83) also exceed state averages, creating a multi-hazard exposure picture.
Hurricane coverage is non-negotiable
With hurricane risk at 91.24, verify your homeowners policy includes wind coverage or secure a separate windstorm policy through the Texas FAIR Plan if needed. Aransas County's elevated flood risk (67.80) makes flood insurance essential; contact your local FEMA office about flood zone status and available coverage options.

Hazard Breakdown
Hurricane risk is Aransas County's dominant natural hazard, ranked at the 91th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 68th percentile nationally. Additional tracked hazards include wildfire (62th percentile), tornado (59th percentile), earthquake (9th percentile).
Preparedness Context
At the 91th percentile nationally for hurricane exposure, Aransas County households benefit from reviewing both homeowners and flood insurance coverage before storm season begins — standard policies often exclude storm surge, which is the leading cause of hurricane fatalities. Aransas County's flood exposure at the 68th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. Hurricane-force winds cause direct property damage, but storm surge causes the majority of hurricane-related deaths. Aransas County households near tidal water or low-elevation areas should verify whether they are in a storm surge risk zone.
Regional Context
At 12.2 points above the Texas state average, Aransas County carries meaningfully higher natural disaster exposure than a typical Texas county.
