A Norumbega Almanac

Dewpoint Comfort Scale

By L.M.

Local weather forecasts almost always leave out an element that is absolutely critical in determining how comfortable a person will be in the warm season. The missing piece?? Dewpoint temperature. Relative humidity is often given but its shortcoming is included in its name....relative.

The RH is entirely dependent upon the temperature. Dewpoint, on the other hand, is a direct measure of moisture in the air.

Based on interviews conducted by this correspondent, it has been found that native northern New Englanders respond to dewpoints temperature as described below.

Note: this scale is intended for use in the warm season on days with a goodly supply of sunshine and relatively light winds.

DEWPOINT PERCEPTION

52 & lower COMFORTABLE

53-56 SLIGHTLY NOTICEABLE

57-59 QUITE NOTICEABLE

60-63 STICKY

64-69 UNCOMFORTABLE

70 + INTOLERABLE
