Oceanside's Climate Data and Its Top-Rated Window Pros
Oceanside sits in IECC climate zone 4A, which sets the energy-performance bar here no matter who ends up installing your windows. A window license file doesn't cover Oceanside on this site, so Google Maps supplies the 10 ranked names you see below. Checked September 2026.

4AIECC climate zone · ENERGY STAR North-Central zone
Oceanside's climate zone, in plain terms
Oceanside falls in IECC climate zone 4A, and ENERGY STAR separately groups Nassau County into its North-Central zone for window certification.
Those two numbers, not the brand on the box, set the U-factor and SHGC worth checking on any quote you get in Oceanside.
A New York-Newark-Jersey City, NY-NJ contractor who can't name either one on request is worth a second question before you sign.
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 0.6 mi away.
What FEMA's risk data says about Oceanside
Nassau 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 Oceanside; 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 Oceanside installer before you settle on a product line.
