Early summer is traditionally a wet and cold time in northwestern Montana, especially June, but from June 15 to July 15 this year, the average daily temperature in West Glacier was 71. 0.6 degrees, 10 degrees higher than the 30-year average. Corby Dickerson, a meteorologist and National Weather Service observation program manager in Missoula, says that while daily high temperatures in the 90s are not unusual for Glacier Park, but they are unusual in early summer. He also said extremely hot days lead to fewer cool nights, which skews the daily average.
