    Global Climate Report – May 2018
    https://www.ncdc.noaa.gov/sotc/global/20180 – 5

    Warmer-than-average conditions engulfed much of the world’s land and ocean surfaces, giving way to the fourth highest May temperature since global records began in 1880. The May 2018 combined average temperature over the global land and ocean surfaces was 0.80°C (1.44°F) above the 20th century average of 14.8°C (58.6°F). The years 2014–2018 rank among the five warmest Mays on record, with 2016 the warmest May at +0.88°C (+1.58°F). May 2018 also marks the 42nd consecutive May and the 401th consecutive month with temperatures, at least nominally, above the 20th century average. The most notable warm temperature departures from average during May 2018 were present across much of the contiguous U.S. and Europe, where temperatures were 3.0°C (5.4°F) above average or higher.

    The global land surface temperature for May 2018 was the coolest May since 2011 and tied with 2013 as the seventh highest in the 139-year record at 1.14°C (2.05°F) above the 20th century average of 11.1°C (52.0°F). The global oceans had their smallest temperature departure for May since 2014 and was also the fourth highest May temperature on record at 0.66°C (1.19°F) above the 20th century average of 16.3°C (61.3°F).

    Europe had its warmest May since continental records began in 1910 at +2.76°C (4.97°F), surpassing the previous record set in 2003 by +0.92°C (+1.66°F). May 2018 marks the first time in May that the continental temperature departure from average is 2.0°C (3.6°F) or higher. May 2018 was the 11th highest monthly temperature departure among all 1,313 months on record. The highest monthly temperature departure for Europe is February 1990 at +3.91°C (+7.04°F).

    The global land and ocean surface temperature for March–May 2018 was 0.82°C (1.48°F) above the 20th century average of 13.7°C (56.7°F) and the fourth warmest such period in the 139-year records, trailing behind 2016 (+1.07°C / +1.93°F), 2017 (+0.91°C / +1.64°F), and 2015 (+0.85°C / +1.53°F). Globally, the average land surface temperature was the fifth highest March–May on record at 1.30°C (2.34°F) above the 20th century average of 8.1°C (46.4°F). The global ocean temperature was 0.64°C (1.15°F) above the 20th century average of 16.1°C (61.0°F) and was also the fourth highest on record.

    The global land surface temperature during January–May 2018 was 1.21° (2.18°F) above the 20th century average of 6.0°C (42.8°F)—tying with 2002 as the fifth highest such period since global records began in 1880. According to NCEI’s Regional Analysis, five of six continents had a January–May temperature that ranked among the eight warmest such periods on record, with Oceania having its second warmest such period on record. Across the oceans, the January–May 2018 global oceans temperature was 0.60°C (1.08°F) above the 20th century average of 16.0°C (60.8°F) and the fifth warmest such period on record.

    Global Climate Report: May 2018 | March – May 2018 [NOAA]

    Much of North America had warmer-than-average conditions during May 2018. According to NCEI’s Regional Analysis, May 2018 temperature North America was 1.74°C (3.13°F) above average—the second highest May temperature, behind the record year 1998 (+1.94°C / +3.49°F).

    Europe had its warmest May since continental records began in 1910 at +2.76°C (4.97°F), surpassing the previous record set in 2003 by +0.92°C (+1.66°F). May 2018 marks the first time in May that the continental temperature departure from average is 2.0°C (3.6°F) or higher. May 2018 was the 11th highest monthly temperature departure among all 1,313 months on record. The highest monthly temperature departure for Europe is February 1990 at +3.91°C (+7.04°F).

The May 2018 combined average temperature over the global land and ocean surfaces was 0.80°C (1.44°F) above the 20th century average of 14.8°C (58.6°F). The years 2014–2018 rank among the five warmest Mays on record, with 2016 the warmest May at +0.88°C (+1.58°F). May 2018 also marks the 42nd consecutive May and the 401th consecutive month with temperatures, at least nominally, above the 20th century average.

    Warmer-than-average conditions were present across much of the global land and ocean surfaces during March–May. Record warm temperatures during the three-month period were present across parts of southern Europe, the Middle East, northeastern Africa, China, Mongolia, and scattered across the South America, Atlantic, Indian, and Pacific Oceans. Cooler-than-average conditions were present across western Russia, north Atlantic (off the southern coast of Greenland), central Indian Ocean, and the eastern and central tropical Pacific Ocean. No land or ocean areas had record cold temperatures during March–May 2018. According to NCEI’s Regional Analysis, five of the six continents had a March–May temperature that ranked among the nine warmest such periods on record, with Europe and South America having their third warmest such period on record.

    The global land and ocean surface temperature for March–May 2018 was 0.82°C (1.48°F) above the 20th century average of 13.7°C (56.7°F) and the fourth warmest such period in the 139-year records, trailing behind 2016 (+1.07°C / +1.93°F), 2017 (+0.91°C / +1.64°F), and 2015 (+0.85°C / +1.53°F). Globally, the average land surface temperature was the fifth highest March–May on record at 1.30°C (2.34°F) above the 20th century average of 8.1°C (46.4°F). The global ocean temperature was 0.64°C (1.15°F) above the 20th century average of 16.1°C (61.0°F) and was also the fourth highest on record.

    The average global land and ocean surface temperature for January–May 2018 was 0.77°C (1.39°F) above the 20th century average of 13.1°C (55.5°F)—tying with 2010 as the fourth highest global land and ocean temperature for January–May in the 1880–2018 record.

    The top five warmest January–May periods were: 2016 (1st), 2017 (2nd), 2015 (3rd), 2010 (4th), and 2018 (4th).

    Arctic sea ice extent for May 2018 was 12.2 million square kilometers (4.7 million square miles). This was the second lowest May extent in the 39-year satellite record, and is 310,000 square kilometers (120,000 square miles) above May 2016, the record low for the month. [https://nsidc.org/arcticseaicenews/2018/06/]

    Sea ice extent in the Southern Ocean grew steadily in May at the rate of 123,000 square kilometers (47,000 square miles) per day, somewhat faster than the 1981 to 2010 average growth rate of 108,000 square kilometers (42,000 square miles) per day. This pushed Antarctic ice extent from third lowest at the start of the month to sixth lowest by June 1. [https://nsidc.org/arcticseaicenews/2018/06/]

    Contiguous U.S. had its warmest May on record

    Each state was warmer than average, record precipitation in the East

    In May, the U.S. sizzled with record warmth. It also had drenching rains in the East,
    with lingering drought conditions in the Southwest and Great Plains.

    May 2018
    The average May temperature across the contiguous U.S. was 65.4 degrees F, 5.2 degrees above average, making it the warmest May in the 124-year record, according to scientists at NOAA’s National Centers for Environmental Information. This surpassed the previous record of 64.7°F set in 1934, during the dust bowl era. There were more than 8,590 daily warm station records broken, or tied, in May.

    The average precipitation for May was 2.97 inches (0.06 inch above average), which ranked near the middle of the record books. Two weather systems, including Subtropical Storm Alberto, helped bring record and near-record rain across the Southeast and Mid-Atlantic. Meanwhile, more than a quarter of the contiguous U.S. remained in drought.
