Hopkinton's climate zone, in plain terms
Middlesex County's normal precipitation runs about 48.9 inches a year, with 48.3 inches of snow, which is a separate question from energy performance but still shapes which window details matter in Hopkinton.
Moisture and glass performance are handled by different parts of a window's spec sheet, and a Hopkinton 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 4.3 mi away.
What FEMA's risk data says about Hopkinton
Middlesex County's hail risk sits at Very Low and its wildfire risk at Relatively Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Hopkinton; 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 Hopkinton installer before you settle on a product line.

The order below weighs a Google rating against its review count, the same way this site weighs a U-factor against a brochure claim: on the number, not the name. Treat it as a rating, never as proof of a license, bond or HVHZ approval.
