Hyattsville's climate zone, in plain terms
Prince George's County's normal precipitation runs about 45.6 inches a year, with 9.7 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Hyattsville.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Hyattsville 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 3.4 mi away.
What FEMA's risk data says about Hyattsville
FEMA rates Prince George's County's hurricane risk as Relatively Moderate and its wind risk as Relatively 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 Hyattsville home.
Ask specifically about design pressure and impact rating for Hyattsville, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Relatively Moderate
- Strong wind
