Risk Overview
About Natural Disaster Risk in Jefferson County, Oklahoma
Jefferson County has very low disaster risk
With a composite risk score of just 20.90, Jefferson County ranks as very low—substantially below both the national average and Oklahoma's state average of 55.47. This favorable risk profile reflects relatively lower exposure across most major natural hazard categories.
Among Oklahoma's safest counties
Jefferson County's score of 20.90 places it among the lowest-risk counties statewide, well below the state average of 55.47. This makes it one of the more resilient areas in Oklahoma from a natural disaster perspective.
Lower risk than nearby counties
Jefferson County's risk score of 20.90 is substantially lower than Jackson County (86.04) to the north and comparable to Johnston County (25.38) nearby. The county enjoys a notably safer natural disaster profile than most surrounding areas.
Wildfire is the primary hazard
Wildfire risk reaches 78.24—the county's highest hazard exposure—though tornado risk (54.29) and hurricane risk (32.71) remain moderate. Overall, hazard exposure in Jefferson County is manageable compared to state and national averages.
Standard coverage likely sufficient
A basic homeowners policy covering wind and hail damage provides solid protection in Jefferson County's lower-risk environment. However, residents in wildland-urban interfaces should still consult an agent about wildfire mitigation and coverage options.

Additional tracked hazards include earthquake (34th percentile), hurricane (33th percentile), flood (14th percentile).
Preparedness Context
At the 78th percentile nationally for wildfire, Jefferson County residents should verify whether their insurance policy includes replacement cost coverage for structures and whether the insurer still writes new policies in this fire-risk zone. A secondary tornado exposure at the 54th percentile nationally means Jefferson County residents face hazards from two distinct natural peril categories during different seasons. Local USFS or Cal Fire (where applicable) fire risk maps and seasonal Red Flag Warning alerts from the National Weather Service are two free resources Jefferson County residents can use to stay ahead of rapidly changing wildfire conditions.
Regional Context
Jefferson County is 34.6 composite risk points below the Oklahoma state mean, meaning most other Oklahoma counties face higher natural hazard exposure.
