Although most summer days are comfortably humid on the Low Plateau, episodes of heat and high humidity can occur with heat index values > . Since 1981, the highest air temperature was on 08/06/2001, and the highest daily average mean dew point was on 08/01/2006. July is the peak month for thunderstorm activity which correlates with the average warmest month of the year. Since 1981, the wettest calendar day was on 09/17/2004. During the winter months, the plant hardiness zone is 5b with an average annual extreme minimum air temperature of . Since 1981, the coldest air temperature was on 01/21/1994. Episodes of extreme cold and wind can occur with wind chill values less than . The average snowiest month is January which correlates with the average coldest month of the year. Ice storms and large snowstorms depositing ≥ of snow occur nearly every year, particularly during nor’easters from December through March. Glaciated Pocono Plateau Region According to the Trewartha climate classification system, the Glaciated Pocono Plateau region of the central and western Poconos has a Temperate Continental climate (Dc) with warm summers (b), cold winters (o) and year-around precipitation (Dcbo). Dcbo climates are characterized by at least one month having an average mean temperature ≤ , four to seven months with an average mean temperature ≥ , all months with an average mean temperature < and no significant precipitation difference between seasons. Although most summer days are comfortably humid on the Pocono Plateau, episodes of heat and high humidity can occur with heat index values > .
