First 80

Yesterday, Tuesday, May 18, the official high temperature at Hector Int’l was 80 degrees which was the first 80 degree or warmer day in Fargo Moorhead this year. The average first day with a high at or above 80 degree is May 5. Our first 50, 60 and 70 degree day this year all occurred remarkably close to the long-term average for such events, therefore this was our first milestone that occurred noticeably later than the average.

Last year our first 80 degree day occurred on April 23 and in 2008 it was on May 16. Since 1881, on only six occasions has the first 80 of the season occurred during June, although, that has not happened since 1983. Since 1881 the average number of days during the year with a high temperature at or above 80 degrees is 61. The cool summer of 2009 brought only 52 such days to this area and the odds favor us experiencing more 80s this year.
