Clearwater's climate zone, in plain terms
Tampa-St. Petersburg-Clearwater, FL runs a January average near 62°F and climbs to about 83°F by July, a swing that adds up to roughly 447 heating degree days most winters, with 3,701 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Clearwater, separate from anything a brochure claims.
Zone 2A's requirement is the floor; Clearwater's specific load is what tells you whether beating that floor is worth the extra cost.

What FEMA's risk data says about Clearwater
Pinellas County's hail risk sits at Relatively High and its wildfire risk at Relatively Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Clearwater; wildfire risk matters more for the frame material and nearby vegetation than for the glass itself.
Either way, it's a reasonable question to bring to a Clearwater installer before you settle on a product line.
