Natural Disaster Risk in Ilwaco

Natural Hazard Profile: Ilwaco, Washington

Located in the Pacific Northwest in Pacific County, Ilwaco is a small community of about 1,555. The oceanic climate that characterizes this part of Washington — marked by mild, rainy winters west of the Cascades and semi-arid conditions to the east — directly influences the types and severity of natural hazards present, making Ilwaco a community where hazard awareness has real practical value.

Ilwaco's overall natural disaster risk is rated 4.9/10 (Moderate) by FEMA's National Risk Index. Coastal tsunami exposure is the dominant hazard concern, with the regional tectonic environment capable of generating both local and distant-source tsunami waves. Secondary hazards include coastal flood and earthquake.

Relative to other U.S. communities, Ilwaco's natural disaster risk is near the U.S. national average of 4.5/10, slightly below the 5.8/10 state average. The hazard distribution here is led by tsunami and coastal flood, as measured by FEMA across Pacific County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

Ilwaco'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 tsunami exposure is adequately protected is a worthwhile step for property owners.
