Florida Wind Speed Map — ASCE 7 Explained

ASCE 7 design wind speeds for Florida are determined based on historical hurricane data and probabilistic wind hazard analysis. The design wind speed is the 3-second gust wind speed with a 700-year return period for Risk Category II buildings (most residential and commercial buildings). The design wind speed varies by location — coastal areas near the Gulf of Mexico and Atlantic Ocean have higher design wind speeds than inland areas. The Florida Keys have the highest design wind speeds in the continental United States (180+ mph). Use our WindCheck FL calculator to find the ASCE 7 design wind speed for your specific Florida project address.

The design wind speed determines the wind loads that your building must be designed to resist. Higher wind speeds mean higher wind loads, which require stronger structural systems, more robust connections, and higher-rated impact windows and doors. For Florida homeowners, the design wind speed also affects your homeowner's insurance premium — buildings in higher wind zones typically have higher insurance premiums. Buildings designed and constructed to resist the design wind speed may qualify for insurance discounts.
