Here in the Northern Plains, summers often bring a lot of cool weather. The average number of days with a high temperature cooler than 80 degrees during June, July and August is 43 in Fargo and 46 in Grand Forks. That's about half for Grand Forks and just below half for Fargo. So far this summer, there have been just seven days cooler than 80 degrees in Fargo and eight in Grand Forks.
This is the fewest on record to this date in summer for Grand Forks, and in Fargo, it is the fewest since there were just six to date in 1988. The lack of cool afternoons has been very hard on crops in the region and is one of the factors, in addition to the dry topsoil and lack of rain, that are pushing the agricultural summer into a major disappointment across the region.
