Weather Talk: Daily low temp of 70 degrees or warmer uncommon in F-MA daily low temperature of 70 degrees or warmer is uncommon in Fargo-Moorhead. We average only three per year, and even that number is skewed somewhat by a handful of years with higher totals. Since 1881, there have been 33 years without a single day with a low at or above 70 degrees, including the recent summers of 2008 and 2009.
One reason for this is that truly humid days (dew points above 70 degrees) are infrequent. Higher moisture content in the air is a key ingredient in keeping the temperature warmer overnight.
We do actually experience more 70-degree mornings than the statistics indicate, but daily high and low temperatures are recorded from midnight to midnight, and frequently our 70 degree mornings occur ahead of a cold front that often will lead to the temperature falling below 70 degrees before midnight the following night.
