NCDC Releases May 2014 Global Climate Report

May 2014 Global Blended Land and Sea Surface Temperature Percentiles Map

According to NOAA scientists, the globally averaged temperature over land and ocean surfaces for May 2014 was the highest for May since record keeping began in 1880. It also marked the 39th consecutive May and 351st consecutive month with a global temperature above the 20th century average. The last below-average global temperature for May occurred in 1976 and the last below-average temperature for any month occurred in February 1985.

The majority of the world experienced warmer-than-average monthly temperatures, with record warmth across eastern Kazakhstan, parts of Indonesia, and central and northwestern Australia. Scattered sections across every major ocean basin were also record warm. Part of the northeastern Atlantic, small sections of the northwestern and southeastern Pacific, and the ocean waters off the southern tip of South America were cooler or much cooler than average.

This monthly summary from NOAA's National Climatic Data Center in Asheville, North Carolina, is part of the suite of climate services NOAA provides to government, the business sector, academia, and the public to support informed decision making.

Note: official monthly data for China were not received on time for inclusion in this analysis. For the purposes of this report, NCDC estimated data for China using daily reports from its GHCN-Daily dataset. When official monthly data are received from China, they will replace the NCDC estimates. The contents of this report will not be updated, but the long-term record at these locations will reflect the official data.
