Surprise's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups Maricopa County into its Southern zone, the U-factor and SHGC target worth checking against any quote you get in Surprise. Below that spec discussion sit 8 installers, their order set by Google rating, since Surprise is outside this site's window license file. A high rating is worth a look, not a finished decision.

Surprise's climate zone, in plain terms
Maricopa County's normal precipitation runs about 9.6 inches a year, with 0.0 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Surprise.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Surprise buyer benefits from checking both instead of assuming one implies the other.
Data: U.S. EPA / DOE, ENERGY STAR, ENERGY STAR Version 7.0 Climate Zones by County/ZIP (Windows, Doors, and Skylights) (V7.0); Pacific Northwest National Laboratory (DOE Building America), Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270) (2021 IECC), from the nearest NOAA station 8.4 mi away.
What FEMA's risk data says about Surprise
FEMA rates Maricopa County's hurricane risk as Very Low and its wind risk as Very High.
Neither rating changes a window's energy label, but both are exactly what impact-resistance and design-pressure ratings are built to answer for a Surprise home.
Ask specifically about design pressure and impact rating for Surprise, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Very Low
- Strong wind
- Very High
- Winter weather
- Relatively Low
