Wisdom, Montana

Wisdom, owing to its high altitude and northerly location, has a subalpine climate (Köppen Dfc) with long, cold, dry winters and short summers with very warm afternoons and cold, clear mornings. With over 277 mornings each year below freezing and only July ever completely frost-free, Wisdom is in terms of frequency of frost one of the coldest places in the United States. During major cold waves, Wisdom’s location in an enclosed valley can make for exceptionally cold temperatures: −55 °F (−48.3 °C) was reached during a great cold wave on December 23, 1983, and −50 °F or −45.6 °C has been reached during seven years, though not since February 4, 1989. Typically there are 47 mornings falling to or below 0 °F or −17.8 °C, and as many as seven fall as low as −25 °F or −31.7 °C, whilst 69.8 afternoons do not top freezing, a tally twice as large as central Montana areas affected by warm chinook winds.

Minimum temperatures during spring do not typically stay above freezing until well into June, although the average last spring ice day date is April 1 and the first fall ice day November 1. Low winter precipitation limits both snowfall and snow depth: the annual mean fall is 42.3 inches or 1.07 metres, and the mean peak snow cover 11 inches or 0.28 metres, with the most snow on the ground being 32 inches (0.81 m) on January 2, 1943. Snow cover is usually gone by the end of March, and despite occasional light snowfalls in May, snow on the ground in that month has not been recorded since 1953. Precipitation is heaviest during the spring, but the enclosed valley location means most moisture is always captured before reaching Wisdom: the wettest month since records began in 1923 has been May 1981 with 4.32 inches (109.7 mm), whilst the wettest calendar year has been 1967 with 15.74 inches (399.8 mm) and the driest 1974 when only 5.60 inches (142.2 mm) fell.

Although summer nights are chilly and even frosty, days can be very warm or even hot, although only 1.3 afternoons typically rise above 90 °F or 32.2 °C and 100 °F or 37.8 °C has never been recorded: Wisdom’s hottest temperature is 98 °F or 36.7 °C on July 13, 2002, and the hottest minimum 62 °F or 16.7 °C on July 23, 1936. On average only two mornings remain above 50 °F or 10 °C each summer, and Wisdom has never recorded so high a minimum between October 20 and May 4 inclusive. By the end of August mornings fall to freezing in five-eighths of all years, and in seven-eighths by the end of September, with the weather continuing to cool into winter with the first minimum under zero expected on November 10.
