Located in the western mountain region near the Pacific Coast in San Luis Obispo County, Los Osos is a city of approximately 14,197 residents. The Mediterranean climate that characterizes this part of California — marked by dry summers and mild, wet winters with pronounced drought cycles — directly influences the types and severity of natural hazards present, making Los Osos a community where hazard awareness has real practical value.

Los Osos's overall natural disaster risk is rated 5.7/10 (Moderate) by FEMA's National Risk Index. Prolonged drought is the primary hazard risk, shaped by low annual rainfall, high evaporation rates, and increasing temperature trends that deepen and lengthen dry periods. Secondary hazards include landslide and tsunami.

Relative to other U.S. communities, Los Osos's natural disaster risk is above the U.S. national average of 4.5/10, near the 5.9/10 state average. The hazard distribution here is led by drought and landslide, as measured by FEMA across San Luis Obispo County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

Los Osos's moderate risk profile means that while catastrophic events are less frequent, they do occur. Standard homeowners insurance typically covers many common hazards here, but confirming that drought exposure is adequately protected is a worthwhile step for property owners.
