Dothan, AL

Earthquake hazard, typical weather and growing season from public federal data. Population 68,001.

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 low

Design category B

Low seismic hazard. Earthquakes are infrequent and usually minor here, but the building code still applies light seismic detailing to new construction. The ASCE 7 Seismic Design Category here is B. (Short-period design value Ss ≈ 0.083 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

92.8° in July, 38.2° in January

Heads up: the nearest station with a full 30-year record is HEADLAND, AL US, about 15.9 miles from here. Treat these as regional rather than local — terrain, elevation and water can change a lot in that distance.

Thirty-year averages, not a forecast. Any individual year can differ substantially.
