The hottest temperatures in our region are more likely to happen during July and the first half of August. Our weather pattern at the moment does not favor days of excessive heat. Historically, however, several days in the 90s and even a few in the 100s have happened very late in August and even in September. So far this year, there have been no days in the 100s and only six in the 90s: one in May, three in June and two in July. The most recent 90-degree day was July 15.
It is likely, though not guaranteed, that our region will have at least one or two more days in the 90s. It is possible, but not likely, that it will get into the 100s. The latest 100-degree day on record for Fargo-Moorhead is 101 degrees on Sept. 22, 1936. The latest 90-degree day happened more recently on Oct. 11, 2015.
