Warm Summer 2006

Summer is quietly coming to a close under sunny skies across much of Minnesota. June through August 2006 will finish as the warmest meteorological summer on record for Duluth and tied for the third warmest summer on record for the Twin Cities. The main reason for the warmth is the very mild overnight lows. The June through August average minimum temperature for the Twin Cities at the International Airport was the warmest on record. Summer 2005 finished in 10th place last year. The normal average summer temperature for the Twin Cities is 70.7. 2006 will be 3.6 degrees above normal. With August finishing about a degree and a half above normal this will be the 15th consecutive month at or above normal at the Twin Cities.

The peak of the summer heat arrived in the last nine days of July when each day was 90 or above. The last time there was a steak of nine 90 degree or warmer days in a row in the Twin Cities was in 2005. The warmest temperature of the summer was 101 on July 31. The last time the mercury cracked the century mark in the Twin Cities was July 13, 1995. The warmest statewide temperature for the summer of 2006 was 107 at Browns Valley on July 31.
