California Wildfire Hazard Profile
Hazard Data · Model Version 2.5
Overview
California faces severe wildfire hazard driven by Mediterranean climate, extensive wildland-urban interface (WUI) development, and drought conditions. The state has experienced a marked increase in large wildfire frequency since 2000, consistent with climate warming trends documented by Abatzoglou & Williams (2016, PNAS). CAL FIRE and NIFC data show California consistently leads US states in wildfire-related insured losses.

Hazard Scoring Approach
Calchis computes a Calchis Hazard Score (0–10) for wildfire hazard at any US address. The score is composed of weighted sub-components derived from federal data sources and published research. All score components are transparent and returned in API responses.
These are hazard scores — physical intensity likelihood only. They do not include property exposure or vulnerability data. We never call a hazard score a risk score. See the full methodology for scoring details.
