What the numbers mean for an outdoor sauna project
Burlington has a high climate load. Its Climate Stress Score of 57.4 is above the indexed-metro median of 37.9. The January normal low is 12.9°F, and 4 months have a normal low below freezing.
The primary planning issue in this profile is winter temperature and freeze exposure. The standardized 9 kW session estimate is $3.87, above the indexed-metro median of $2.46; this uses the Vermont statewide residential electricity average, not a city utility quote. The selected snowfall record reports 87.5 inches annually.
For construction or maintenance work that is easier in moderate conditions, the monthly normals point to April, May, June, August. This is a climate-screening observation, not a construction schedule or permit recommendation.
