The global land surface temperature for June was 1.07°C (1.93°F) above the 20th century average of 13.3°C (55.9°F), the warmest June on record. This is the second month in a row that the global land temperature was the warmest on record for that month. The Northern Hemisphere average land temperature, where the majority of Earth's land is located, was record warmest for June. This makes three months in a row -- April, May, and June -- in which record-high monthly land temperature records were set. Most areas experienced much higher-than-average monthly temperatures, including most of North America and Eurasia, and northern Africa. Only northern and western Europe, and the northwestern United States were notably cooler than average.
Across the world's oceans, the June average global sea surface temperature was 0.47°C (0.85°F) above the 20th century average of 16.4°C (61.5°F), the 10th warmest June on record. Ocean temperatures were notably below average in the northeastern Pacific Ocean and much higher than average in the northeast Atlantic and in the Labrador Sea near Greenland. The region of the equatorial Pacific Ocean where ENSO (El Niño/La Niña-Southern Oscillation) conditions are measured also trended higher than average in June. NOAA's Climate Prediction Center issued an El Niño watch, and stated that there is an increased chance for El Niño beginning in JulySeptember 2012. NOAA listed global highlights of the report as follows:
- The average combined global land and ocean surface temperature for June 2012 was 0.63°C (1.13°F) above the 20th century average of 15.5°C (59.9°F). This is the fourth warmest June since records began in 1880.
- The Northern Hemisphere land and ocean average surface temperature for June 2012 was the all-time warmest June on record, at 1.30°C (2.34°F) above average.
- The globally-averaged land surface temperature for June 2012 was also the all-time warmest June on record, at 1.07°C (1.93°F) above average.
- ENSO-neutral conditions continued in the eastern equatorial Pacific Ocean during June 2012 as sea surface temperature anomalies continued to rise. The June worldwide ocean surface temperatures ranked as the 10th warmest June on record.
- The combined global land and ocean average surface temperature for JanuaryJune 2012 was the 11th warmest on record, at 0.52°C (0.94°F) above the 20th century average.
