After September, the likelihood of Fairbanks achieving a high temperature over 60F (even 50F) rapidly diminishes. Here is the breakdown of high temperatures broken down into common 10-degree categories. All values correspond to the January through September time period. There are three comums for each category; A) 2013 values, B) long-term (1920-2012) values, and C) normal (1981-2010) values. The chart shows that there have been many more days in the 0s, 10s, 30s, and 80s than is typical; and far fewer days in the 50s and 60s. This is a consequence of the abrupt transition from Winter to Summer with nary a Spring season.
