Ranked from NOAA 1991-2020 Climate Normals
Highest Heating Demand in Louisiana
Heating degree days measure how far and how long the outside temperature sits below 65°F across a year, which is the closest single number to how much heat a house has to make. Figures are NOAA 1991-2020 Climate Normals from the weather station nearest each county seat, so they describe a thirty-year average rather than any single year.
