FARGO — On July 6, 1936, the temperature at the Moorhead office of what was than called the U.S. Weather Bureau reached a sweltering 114 degrees. The Weather Bureau, now the Weather Service, was housed at that time in what was the Federal Building on Main Avenue in Moorhead, now the Rourke Museum. The official weather recordings for Fargo-Moorhead were made at that office in Moorhead from 1881 into the early 1940s. Hector Airport, however, started making its own weather recordings in the 1930s, so there is a period of overlap.
Interestingly, the temperature at Hector that afternoon was 115 degrees, but that figure is not in the Fargo climate record because the official Fargo-Moorhead weather station was the one in Moorhead at the time. So, the station record high temperature for Fargo was actually measured in Moorhead. The Grand Forks temperature record was set six days later at 109 degrees.
