Monthly record heat streak ends

WASHINGTON – You wouldn’t know it by the unbearable heat you’re still experiencing, but the 16-month streak of record warmth has been broken.

August’s warmth spread into September, contributing to the warmest year to date for the globe, but it was not enough to continue the record. Even so, September 2016 ranked as the second warmest September on record.

It was 1.60 degrees F above the 20th-century average, missing last year’s record for the month by just 0.07 degrees, according to scientists from NOAA’s National Centers for Environmental Information.

For the year to date, the average global temperature was 1.78 degrees F above average, surpassing the heat record set in 2015 by 0.23 degrees.


More notable findings around the world include:

The globally averaged sea surface temperature tied with 2014 as the second warmest on record for September and warmest on record for the year to date (January–September);

The globally-averaged land surface temperature was record high for September and the year to date);

Record-warm continents: Europe and Asia had their warmest September; Africa had its second, and North America had its third;
