August 2016 Climate Data for Memphis, TN

August Recap

Summer continued full bore in August as the hot weather of June and July continued into the month. In fact, August placed in the top 10 hottest on record in Memphis (#10), meaning that all three summer months were ranked in their individual top 10 warmest. At the end of August, a new record was established for consecutive days above 70°, standing at 82 days. The hottest day of the month was 99° on the 5th.

Both of these streaks rank in the top 3 longest on record. The average temperature of 84.3° for June-August was 2.9° above the climate average and ranks as the 4th hottest summer in Memphis' recorded history.
