In fact, according to the NOAA Climate National Climate Data Center, the average temperature across global land and ocean surface temperatures combined for June 2017 was the third highest for this month in the 138-year period of record, at 0.82°C (1.48°F) above the 20th century average of 15.5°C (59.9°F). The record high was registered in 2016 (+0.92°C / +1.66°F); June 2017 marks the 41st consecutive June and the 390th consecutive month with temperatures above the 20th century average.
Global temperature in June 2017 (land surface): 1.15°C (2.07°F) above the 20th century average
The average June temperature across global land surfaces was 1.15°C (2.07°F) above the 20th century average of 13.3°C (55.9°F), the fourth highest June global land temperature in the 138-year record, behind 2016 (+1.29°C / +2.32°F), 2015 (+1.28°C / +2.30°F), and 2012 (+1.22°C / +2.20°F). Three of the hottest June in the historical record belongs to the last three years…
Five of six continents had a top ten warm June, with Africa experiencing its warmest June since continental records began in 1910. Much of Europe experienced warmer to much-warmer-than-average temperatures, with several locations experiencing record warmth. A heat wave impacted much of western and central Europe during mid-June, with several locations reporting temperatures 30.0°C (86.0°F) or higher.
Global temperature in June 2017 (ocean surface): 0.70°C (1.26°F) above the 20th century average
Across the oceans, the average global ocean surface temperature during June 2017 was 0.70°C (1.26°F) above the 20th century average of 16.4°C (61.5°F)—the third highest June temperature since global records began in 1880.
Global temperature in the first 6 months of 2017 (January-June 2017)
The first six months of 2017 have each ranked among the top three warmest months on record, giving way to the second highest January–June period in the 138-year record at 0.91°C (1.64°F) above the 20th century average of 13.5°C (56.3°F), behind the record year of 2016 by 0.16°C (0.29°F), but ahead of 2015 by 0.05°C (0.09°F).
Much of the world's land and ocean surfaces had warmer to much-warmer-than-average conditions during the January–June 2017 period, with limited areas experiencing near to cooler-than-average conditions. Record warmth across the land surface was observed across much of Mexico, western Europe, eastern Russia, South Korea, Madagascar, and some areas across northern and east central Africa, eastern China, and eastern Australia.
