What zone 5A means for a Hanover window
Plymouth County's normal precipitation runs about 52.3 inches a year, with 50.9 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Hanover.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Hanover 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 7.7 mi away.

Plymouth County's hail risk sits at Very Low and its wildfire risk at Very Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Hanover; 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 Hanover installer before you settle on a product line.
