Risk Overview

About Natural Disaster Risk in Oswego County, New York

Oswego: Moderate Hazard Exposure Nationwide

Oswego County scores 67.56 on composite disaster risk, placing it just slightly below the national average in the relatively low risk category. This score reflects moderate but not extreme exposure to multiple hazard types, with flooding representing the most serious threat. Oswego residents face natural disaster risks that are somewhat lighter than the nation overall.

Oswego Below New York's Average Risk

Oswego scores 67.56 compared to New York's state average of 69.42, positioning it slightly below the statewide norm and among the safer New York counties. This below-average profile gives Oswego residents a relative advantage in terms of broad hazard exposure. However, specific localized threats still deserve serious attention and preparation.

Oswego: Mid-Range Risk for Central NY

Oswego (67.56) sits between lower-risk Ontario (63.55) and higher-risk neighbors Oneida (86.32) and Onondaga (91.25), representing a moderate position in central New York's risk spectrum. Oswego's profile is somewhat safer than the densest urban areas nearby. Your county's risk level places it in a comfortable middle ground for the region.

Flooding Dominates the Hazard Profile

Oswego's primary concern is flooding, with a risk score of 82.12 that significantly exceeds all other hazards in the county. Earthquakes (65.30) and hurricanes (60.66) present moderate secondary risks, while tornadoes (43.10) and wildfires (35.69) remain relatively low. Flood preparedness and protection are the clear priority for Oswego households and businesses.

Flood Insurance Protects Your Most Valued Asset

Oswego residents must prioritize flood insurance given the county's 82.12 flood risk score, as standard homeowners coverage excludes flood damage entirely. A comprehensive homeowners policy with solid wind coverage addresses other secondary risks adequately. Contact an insurance agent today to obtain flood insurance quotes—coverage is often affordable and essential for financial protection.

Risk Advisory: Oswego County

Risk Verdict

Oswego County's FEMA risk score places it at the 68th percentile nationally, indicating lower-than-typical exposure for a U.S. county. A moderate composite score often means one or two hazard categories are doing the heavy lifting — knowing which ones matters for preparation.

Hazard Breakdown

Flood risk is Oswego County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 65th percentile nationally. Additional tracked hazards include hurricane (61th percentile), tornado (43th percentile), wildfire (36th percentile).

Preparedness Context

At the 82th percentile nationally for flood risk, Oswego County residents benefit from understanding their specific flood zone status. Even one inch of floodwater causes significant structural damage to properties outside officially designated high-risk zones. Alongside flooding, earthquake exposure at the 65th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. A tested family preparedness plan specific to Oswego County's primary hazards — including how to shelter in place or evacuate, and who to call — provides more real protection than a general emergency kit sitting unused on a shelf.

Regional Context

Oswego County sits within 1.9 composite points of the New York state average, suggesting the county's hazard exposure is representative of the broader regional pattern.
