Since records began, Fargo Moorhead has hit 110 degrees or higher only three times. Two of those times were during the most intense heat wave recorded in this region. For fifteen straight days, July 4-18, 1936, the temperature was at or above 90 degrees and on nine of those days it was over 100 degrees. On two occasions, July 6 and July 10 the temperature reached 114 and 110 degrees.
The other 110 degree day occurred during the summer of 1917, but unlike 1936, that particular summer was not a hot one. As a matter of fact, to our east, the year 1917 was the coldest year of the 20th century in the Twin Cities and Duluth, Minnesota. Yet, mixed in with a mostly cool summer was a brief but intense heat wave when 11 out of 13 days in late July had highs in the 90s, with July 28, 1917 topping off at 110 degrees, the second warmest day on record.
