What zone 1A means for a Miami Beach window
Miami-Fort Lauderdale-West Palm Beach, FL runs a January average near 67°F and climbs to about 83°F by July, a swing that adds up to roughly 139 heating degree days most winters, with 4,187 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Miami Beach, separate from anything a brochure claims.
Zone 1A's requirement is the floor; Miami Beach's specific load is what tells you whether beating that floor is worth the extra cost.

HVHZFlorida High-Velocity Hurricane Zone
Does Miami Beach fall inside the HVHZ?
Miami Beach, FL sits inside Florida's High-Velocity Hurricane Zone, which means yes is the answer to whether the stricter statewide testing tier applies here.
In practice, that means a window installed in Miami Beach needs a Florida product approval marked for the HVHZ, or a Miami-Dade or Broward Notice of Acceptance, not just a standard statewide approval.
Ask any Miami Beach installer to show that specific paperwork for the exact product they're proposing, not a general Florida approval.
