In an effort to recognize specific key dates which identify the natural seasons of the year, the thermal record of western Oregon and Washington is subjected to automated clustering techniques. Individual natural seasons of the year are recognized by the manner in which weekly temperature maxima, minima, and means are grouped using automated clustering techniques. Beginning and ending dates of the natural seasons of western Oregon and Washington are presented.
