Both Fargo and Grand Forks have recorded two days with temperatures in the 100s already this month. Historically, 100-degree weather in June in our region is rare. In Fargo-Moorhead, this is something that has happened in only seven June months since records began and multiple century days in June has happened only in 1931, 1933, and now 2021. Grand Forks has recorded 100 degrees in June in only six years and multiple times in just two; 1933 and 2021. Century temperatures have been much more common during the months of July and August.
To get to 100 degrees in our climate usually requires dry soil, which is heated very efficiently by the sun. However, June is our rainiest month of the year, on average. Extreme heat in June usually requires a drought and this year, rainfall through May and early June has been among the driest on record. It is possible there will be more days of 100-degree weather this month.
