Local Heat Waves

Long stretches of 90 degree weather in Fargo Moorhead is somewhat unusual.   Since 1881, there have been only 20 instances where the high temperature has been at or above 90 degrees for six consecutive days or longer. 

The last time this area experienced a stretch of six straight 90 degree days was in July, 2006.  We also had a stretch of six straight 90 degree days in August 2001 and August 2003.  Our two warmest summers, 1988 and 1936 each recorded two such stretches.  Although the summer of 2012 ranked as the 4th warmest on record, the longest 90 degree stretch was just four days, a testament to how rare long hot stretches are in this area.

The most brutal heat wave recorded in this area was back in 1936 when 15 straight days of 90 degree temperatures was observed with eight of those days exceeding 100 degrees.  The second longest stretch of extreme heat locally occurred during the summer of 1976 when nine straight days above 90 degrees occurred during late August of that summer.
