Long stretches of 90-degree weather in Fargo-Moorhead are 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. The longest 90-degree stretch this summer has been two days: June 7 and 8.

Our two warmest summers, 1988 and 1936, each recorded two such six-day periods in the 90s.

The most brutal heat wave recorded in this area was back in 1936 when 15 consecutive days of 90-degree temperatures were observed with eight of those days exceeding 100 degrees.

The second longest stretch of extreme heat locally occurred during late August 1976 when nine straight days above 90 degrees occurred. Long periods of hot weather have historically occurred during periods of drought.
