Gardens, snow, and the best days of the year in Melville.
Temperatures and rainfall come from NOAA’s gridded climate normals for Melville itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Islip Li Macarthur Airport, NY (16 mi, snow) and Farmingdale Airport, NY (3 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000. Today’s forecast: National Weather Service.
