Heating and cooling a home in Kasaan
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Kasaan, 100% of that work is heating and 0% is cooling, so the furnace matters far more than the air conditioner.
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.

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 Thorne Bay, AK (10 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
