Climate risk in Portland, Oregon.
Rising wildfire smoke, heat waves, and Cascadia seismic risk.
Portland's dominant emerging risks are wildfire smoke intrusion, heat-dome events (2021), and Cascadia Subduction Zone seismic exposure. Direct wildfire is on the fringe; flood is moderate.
Peril breakdown
Willamette flooding history; localized.
Direct wildfire on the fringes; smoke intrusion metro-wide during Cascade fire seasons.
Occasional severe wind; not hurricane.
2021 heat dome showed non-linear risk. AC penetration is low.
Cascadia Subduction Zone. Retrofit standards vary.
Insurability
Standard market operating. Wildfire-exposed fringes seeing tighter underwriting. Seismic coverage is a separate policy.
20-year outlook
Smoke days projected to rise; heat wave frequency rising. Seismic is stable but low-probability high-consequence.
