NOAA’s gridded normals don’t cover this state, so temperatures and rainfall come from the nearest weather station. Snow, frost dates and day counts come from NOAA’s weather station at Kamaoa Puueo 5.1, HI (3 mi, snow) and South Kona 2 2.32, HI (9 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020.
