Global temperature highlights: December-February
- The combined average temperature over global land and ocean surfaces for December-February was the eighth highest on record for this period, at 1.03°F (0.57°C) above the 20th century average of 53.8°F (12.1°C). The margin of error associated with this temperature is +/- 0.18°F (0.10°C).
- The global land temperature was the 10th highest for December-February on record and highest for the period since 2009, at 1.57°F (0.87°C) above the 20th century average of 46.4°F (8.1°C). The margin of error is +/- 0.40°F (0.22°C).
- The Southern Hemisphere middle latitude land areas were record warm for austral summer. The Northern Hemisphere land areas ranked as 11th warmest, with some sharp north-south patterns in the polar jet stream that contributed to below-average temperatures in some regions and above-average temperatures in others.
- Summer 2013/14 was warmer than average for Australia, with a nationally-averaged temperature that was 0.81°F (0.45°C) above the 1961-1990 average. This marks the 15th warmest summer for the country since records began in 1910 and is cooler compared with last year's record-setting summer that was 2.59°F (1.44°C) above average. This summer, New South Wales, Victoria, and South Australia all observed summer temperatures among their eight warmest on record, while the Northern Territory had its 28th coldest (77th warmest) average summer temperature on record.
- Austria observed its second warmest winter in the country's 247-year period of record, behind only the winter of 2006/07, at 4.9°F (2.7°C) above the 1981-2010 average. Switzerland had its third warmest winter since national records began in 1864, while winter 2013/14 in the Netherlands tied with 1990 for its second warmest since national records began in 1901.
- In northern Europe, Denmark reported its fifth warmest winter for 2013/14 since records began in 1874, at 6.7°F (3.7°C) above average.
- The United States, conversely, had its 34th coldest winter in its 119-year period of record, at 1.0°F (0.6°C) below average, the coldest winter since 2009/10.
- For the ocean, the December-February global sea surface temperature was 0.83°F (0.46°C), above the 20th century average of 60.7°F (16.0°C), tying with 2005 as the sixth highest for December-February on record. The margin of error is +/- 0.07°F (0.04°C). Similar to February, the average Northern Hemisphere ocean surface temperature outside the tropics (20°N-90°N) was also record warm for the winter season.
