Fort Lauderdale, FL

Earthquake hazard, typical weather and growing season from public federal data. Population 172,389.

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 ≈ 0.043 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.

Typical weather

NOAA/NCEI 1991–2020 U.S. Climate Normals — station FT LAUDERDALE BEACH, FL US, 1.9 mi away.

Growing season zone 11a

365 frost-free days

Heads up: the nearest station with a full 30-year record is LOXAHATCHEE NWR, FL US, about 26.6 miles from here. Treat these as regional rather than local — terrain, elevation and water can change a lot in that distance.

Last spring frost around n/a, first fall frost around n/a. Roughly half of years see frost outside that window.
