Florida Wind Speed by Address

Look up the basic wind speed for any address in Florida, the speed the 2023 Florida Building Code (8th edition) and the American Society of Civil Engineers standard ASCE 7-22 design to. Enter an address or click the map.

Contours in mph. The shaded counties are the High-Velocity Hurricane Zone.

Enter an address or click the map to look up the wind speed.

Speeds come from the code's contour maps (Figures 1609.3(1) to 1609.3(4)) and read within a few mph of the ASCE Hazard Tool. The building department's speed governs; check it before you design.

Risk categories

The risk category depends on what the building is used for, and how many people a failure would put in danger. Higher categories are designed for rarer, stronger storms.

  • Risk Category I: Low hazard to people: barns, sheds, minor storage, screen enclosures
  • Risk Category II: Most buildings: homes, offices, stores, warehouses
  • Risk Category III: Many people or vulnerable people: schools, theaters, larger assemblies
  • Risk Category IV: Essential: hospitals, fire and police stations, emergency shelters

Most homes and commercial buildings are Risk Category II. Table 1604.5 of the code has the full list.

The High-Velocity Hurricane Zone

In Miami-Dade and Broward counties the code doesn't use the map. Section 1620 sets one speed for each county, and every building there is designed for Exposure Category C, or D where ASCE 7 calls for it:

CountyIIIIIIIV
Miami-Dade165175186195
Broward156170180185

Windows, doors, roofing and other products there also need Miami-Dade or Florida product approval for the high-velocity zone.

Wind speed questions

What is the basic wind speed?

The 3-second gust, 33 ft above open ground (Exposure Category C), with the chance of being exceeded the code sets for the risk category: once in 700 years on average for Risk Category II. It's the starting point for the wind pressures on a building, before the effects of height, terrain and the building's shape.

Can I use the speed between two contours?

Yes. The code lets you interpolate between contours, which is what this lookup does, or use the higher contour to be safe.
