Heating and cooling a home in Captain Cook
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Captain Cook, 5% of that work is heating and 95% is cooling, so air conditioning is the bigger bill.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.

Snow, frost dates and day counts come from NOAA’s weather station at Puuhonua-o-honaunau 27.4, HI (6 mi, snow) and Opihihale #2 24.1, HI (16 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020.
