This June has definitely started cool, but no where near as cold as what we experience in June 2009. From June 5 through June 9 that year, the high temperature never got out of the 50s. It was the only time since records began in 1881 that Fargo Moorhead recorded 5 straight days with a high below 60 degrees during the month of June.
Although, not consecutively, there were two other Junes with five total days with a high below 60 degrees in 1915 and in 1897. One of those days during that cold stretch four years ago, June 6, 2009, the high only reached 53 degrees and that was tied for the coldest June high temperature since 1969. The summer of 2009 remained cool and ranks as the 17th coldest on record.
June 1998, on the other hand, recorded three days with high temperature in the 50s, but that summer finished with above average temperatures meaning that a cool start to a summer does not necessarily mean that the rest of the season will follow that trend.
