Temperatures and rainfall come from NOAA’s gridded normals for Casa de Oro-Mount Helix itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at Lakeside 2 E, CA (8 mi, snow) and El Cajon, CA (3 mi, frost, heat and degree days). Sunrise and sunset are calculated from the town’s position.
