Window Wind Load

Miami Wind Load Calculator for Windows & Doors

Generate ASCE 7-22 design pressure calculations for Miami and Miami-Dade County window and door permits. Miami sits in the High Velocity Hurricane Zone (HVHZ) — the strictest wind code jurisdiction in the United States.

Miami-Dade Wind Speed & Design Parameters

Parameter	Value
Design Wind Speed	170–185+ mph (ASCE 7-22)
Exposure Category	C (inland) or D (within 1 mi of water)
Product Approval	Miami-Dade NOA required
Zone	HVHZ — High Velocity Hurricane Zone

What Miami-Dade Inspectors Require

ASCE 7-22 wind pressure calculations for every opening (Zone 4 and Zone 5)
Opening schedule with dimensions, floor level, and required DP ratings
Miami-Dade NOA number for each product specified
HVHZ compliance notes per FBC Section 1609

Coastal vs. Inland Miami-Dade

Exposure D (Coastal) — Miami Beach, Key Biscayne, Brickell waterfront, Bal Harbour, Surfside. Highest design pressures — Zone 5 corners can exceed 100 psf.
Exposure C (Inland) — Hialeah, Doral, Kendall, Homestead, Miami Lakes. Still very high due to 170+ mph wind speeds.

Impact Windows Required

Miami-Dade is entirely within the Wind-Borne Debris Region. All glazed openings must have either impact-rated products with a current Miami-Dade NOA, or approved hurricane shutters with their own NOA.
