Temperatures and rainfall come from NOAA’s gridded normals for Round Valley itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at Bishop Airport, CA (12 mi, frost, heat and degree days). Sunrise and sunset are calculated from the town’s position. Normals are 30-year averages, not a forecast.
