New Orleans is right at the mouth of the Mississippi River at the Gulf of Mexico, at an elevation that ranges from 6 feet below sea level to 20 feet above sea level. New Orleans doesn’t get extreme heat like some other places in the United States, but it gets hot enough and the high humidity can make it feel even hotter, with the heat index or “feels like” temperature getting to near 110 F.

A Hot July

July 2016 was the hottest July in the history of New Orleans. The average temperature in July was a hot 86.7 degrees, which broke the previous record of 85.8 set in 1980. The average low temperature for July was the warmest ever at a warm 79.4 degrees.

Actually, July 2016 was an incredibly warm summer when looking at the overnight lows. New Orleans recorded an incredible 43 nights where the temperature never dropped below 80 degrees. The previous record was 13 nights with the temperature not dropping below 80 degrees in 2010. The record of 43 nights not dropping below 80 F is remarkably warm when you consider that New Orleans only averages 2 nights per summer where the temperature stays above 80 all night.

The Gulf of Mexico was unusually warm in 2016, and this caused more evaporation from the Gulf increasing the humidity and dew point in New Orleans leading to warmer nights.
