This was also the 34th consecutive March with global land and ocean temperatures above the 20th century average. The March worldwide land surface temperature was 1.36°C (2.45°F) above the 20th century average of 5.0°C (40.8°F)—the fourth warmest on record. The worldwide ocean surface temperature was 0.56°C (1.01°F) above the 20th century average of 15.9°C (60.7°F) and the warmest March on record. For the year-to-date, the global combined land and ocean surface temperature of 13.0°C (55.3°F) was the fourth warmest January-March period. This value is 0.66°C (1.19°F) above the 20th century average.... March 2010The combined global land and ocean surface temperature anomaly for March 2010 was 0.77°C (1.39°F) above the 20th century average, resulting in the warmest March since records began in 1880. The previous record was set in 2002 when temperatures were 0.74°C (1.33°F) above the 20th century average. Sea surface temperatures (SST) during March 2010 were warmer than average across much of the world's oceans, with the cooler-than-average conditions across the higher-latitude southern oceans, across parts of the northern Pacific Ocean, and along the western coast of South America. Warmer-than-average conditions were most pronounced in the equatorial portions of the oceans, where the tropical ocean surface temperature (equatorward of 20 degrees latitude) also had its warmest March on record. The March 2010 worldwide SST ranked as the warmest on record, with an anomaly of 0.56°C (1.01°F) above the 20th century average—the previous record was set in 1998. El Niño weakened to moderate strength during March; however, it contributed significantly to the warmth observed in the tropical belt and the overall ocean temperature. According to NOAA's Climate Prediction Center, El Niño is expected to continue through the Northern Hemisphere spring 2010 and transition to ENSO-neutral conditions by the Northern Hemisphere summer 2010. The worldwide land surface temperature was the fourth warmest on record, with a temperature anomaly of 1.36°C (2.45°F) above the 20th century average. During March 2010, warmer-than-average conditions dominated the globe, with the most prominent warmth in northern Africa, the Middle East, South Asia and Canada. Cooler-than-average conditions were present across Mongolia, central and eastern Russia, northern and western Europe, Mexico, the southeastern U.S., northern Australia, and western Alaska.
