Fort Myers, FL

Earthquake hazard, typical weather and growing season from public federal data. Population 68,190.

Flood zone: it depends on the exact parcel

There is no such thing as a flood zone for a whole city. Two houses on the same street can sit in different zones, and it is the single fact here that changes most over a short distance. So this page does not guess one.

Earthquake hazard very-low

Design category A

Very low seismic hazard. Damaging earthquakes are rare at this location and design ground motions are minimal. Ordinary buildings carry essentially no special seismic-detailing requirement. The ASCE 7 Seismic Design Category here is A. (Short-period design value Ss ≈ 0.047 g — the standard headline measure of ground-shaking hazard.)

USGS Seismic Design Web Services (ASCE 7), assuming Site Class D — stiff or unknown soil. Real soil conditions can move the category either way.

This station records temperature and precipitation but not snowfall, so no snow column is shown. That is missing data, not a report of zero snow — Fort Myers may well get plenty.
