What the numbers mean for an outdoor sauna project
Raleigh has a mild climate load. Its Climate Stress Score of 27.4 is below the indexed-metro median of 37.9. The January normal low is 31.6°F, and 1 month has a normal low below freezing.
The primary planning issue in this profile is rain and exterior moisture management. The standardized 9 kW session estimate is $2.26, below the indexed-metro median of $2.46; this uses the North Carolina statewide residential electricity average, not a city utility quote. The selected snowfall record reports 4.5 inches annually.
For construction or maintenance work that is easier in moderate conditions, the monthly normals point to March, April, May, October. This is a climate-screening observation, not a construction schedule or permit recommendation.
