Climate risk in Miami, Florida.
Storm surge, flood, and the hardest insurance market in the country.
Miami's climate exposure is dominated by hurricane surge, king-tide flooding, and a homeowner's insurance market under structural stress. Wind and rainfall risk are elevated across the metro; surge risk varies sharply by elevation and distance from Biscayne Bay.
Peril breakdown
Storm surge, king tides, and sunny-day flooding. FEMA zones cover much of the barrier islands and low-lying interior.
Wildland fire is not a meaningful risk in the developed metro.
Sustained hurricane wind exposure. Post-Andrew code enforced from 2002+; older stock is materially more exposed.
Rising nights above 80°F drive cooling load and health risk. Urban heat island effect is significant in Little Havana, Overtown, Hialeah.
Roughly 6" of local sea-level rise since 1993; NOAA central projection adds another 10-14" by 2050.
Insurability
Citizens Property Insurance is the insurer of last resort for a growing share of the market. Admitted-market non-renewals have accelerated. Flood coverage typically requires NFIP or private flood — homeowner's does not cover surge.
20-year outlook
20-year outlook shows rising surge severity from warmer Gulf and Atlantic sea-surface temperatures, and continued sea-level rise pushing tidal flooding further inland. Insurance market stress is expected to persist through the decade.
If you're buying in Miami
Prioritize post-2002 construction, elevation above the surge zone, impact glass, and a Class-A roof under 10 years old. Get a written homeowner's + flood quote before contract, not after.
