West Palm Beach's climate zone, in plain terms
Miami-Fort Lauderdale-West Palm Beach, FL runs a January average near 66°F and climbs to about 83°F by July, a swing that adds up to roughly 202 heating degree days most winters, with 4,166 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in West Palm Beach, separate from anything a brochure claims.
Zone 1A's requirement is the floor; West Palm Beach's specific load is what tells you whether beating that floor is worth the extra cost.
