Last week’s stretch of eight straight days at or above 80 degrees brought our monthly total of 80 degree days to twelve. Since 1881 this is the fourth highest number of 80s observed during the month of September. The long-term average for 80 degree days this month is six.
This is the most 80s Fargo Moorhead has recorded in September since 12 such days were observed during September, 2002. Plus, this month is only the 5th time since 1980 we have recorded 10 or more days in the 80s during the month of September, so indeed, it has been a very warm month to this point. In fact, this past summer was so cool, that this month has recorded more 80 degree days then either June or August did which both only had ten 80 degree days each.
The last time September had the 2nd most 80s in a year was in 2004.
