NCDC: April Global Temperature Anomalies
- The combined average temperature over global land and ocean surfaces for April 2012 was 14.35°C (57.87°F), which is 0.65°C (1.17°F) above the 20th century average of 13.7°C (56.7°F). The margin of error associated with this temperature is ±0.08°C (0.14°F). The global temperature departure from the 20th century average and the monthly rank were the highest since November 2010, near the onset of first back-to-back La Niñas in 2010.
- The global land surface temperature was 1.39°C (2.50°F) above the 20th century average of 8.1°C (46.5°F), making this the second warmest April, behind 2007. The margin of error is ±0.11°C (0.20°F).
- For the ocean, the April global sea surface temperature was 0.38°C (0.68°F) above the 20th century average of 16.0°C (60.9°F)—the 11th warmest April on record. The margin of error is ±0.04°C (0.07°F).
January–April 2012 Blended Land and Sea Surface Temperature Anomalies in degrees Celsius The January–April map of temperature anomalies shows that warmer-than-average temperatures occurred across the contiguous United States, southern Canada, Mexico, southern South America, the United Kingdom, Scandinavia, northern Russia, and parts of southeastern Asia. Cooler-than-average conditions were observed across Alaska, northern Africa, central Asia, eastern Russia, and most of Australia.
