Temperatures and rainfall come from NOAA’s gridded normals for Compo itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at Bridgeport Sikorsky Mem Airport, CT (12 mi). Sunrise and sunset are calculated from the town’s position. Normals are 30-year averages, not a forecast.
