Forecast, conditions and alerts: National Weather Service. Climate: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000. Temperatures and rainfall come from NOAA’s gridded normals for Charlestown itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at Wilmington New Castle Co Airport, DE (21 mi, snow) and Aberdeen Phillips Fld, MD (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.
