Heating and cooling a home in Wailea
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Wailea, 0% of that work is heating and 100% 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 Makena Golf Crs 249.1, HI (3 mi) away. Normals are 30-year averages, not a forecast.
