Temperatures and rainfall come from NOAA’s gridded normals for Cathlamet itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at Cathlamet 6ne, WA (3 mi, snow) and Ft Clatsop Natl Mem, OR (24 mi, frost, heat and degree days). Sunrise and sunset are calculated from the town’s position. Normals are 30-year averages, not a forecast.
