The globally averaged temperature over land and ocean surfaces for August 2014 was the highest for August since record keeping began, largely driven by record sea surface temperatures, according to the U.S. National Oceanic and Atmospheric Administration (NOAA). June-August 2014 was also the hottest such period on record.

The combined average temperature over global land and ocean surfaces for June-August was the highest on record for this period, at 0.71°C (1.28°F) above the 20th century average of 16.4°C (61.5°F), according to NOAA.

NOAA said the combined average temperature over global land and ocean surfaces for August 2014 was the record highest for the month, at 16.35°C (61.45°F) or 0.75°C (1.35°F) above the 20th century average of 15.6°C (60.1°F). This temperature beat the previous record set in 1998 by 0.04°C (0.07°F).

It also marked the 38th consecutive August with a global temperature above the 20th century average. The last below-average global temperature for August occurred in 1976, according to NOAA scientists.

The Tokyo Climate Center, which is a WMO Regional Climate Centre, also reported that August was the hottest on record. Monthly mean temperatures were extremely high from western Alaska to Eastern Siberia, as well as the western coast of the USA and Mexico. Monthly precipitation amounts were extremely heavy from Western Japan to southern China, it said.

The record was also confirmed by data from NASA’s Goddard Institute for Space Studies.

WMO uses a combination of datasets to compile its annual Statement on the Status of the Global Climate. It will issue its provisional statement for 2014 in November.
