Hottest March On Record!

April 17, 2010 — The U.S. Oceanic and Atmospheric Administration has made an incredible discovery -- The world has never seen a warmer March on record until now.

Last month's combined land and ocean surface temperature were the warmest they've ever recorded. As well, the average ocean temperature was the warmest of all time and the global land surface was the fourth hottest. Additionally, it was the fourth balmiest January - March period on record.

The records span as far back as 1880 and based on the monthly National Climatic Data Centre.

Here are some global temperature highlights from March 2010 according to NOAA:

  • The combined global land and ocean average surface temperature for March 2010 was the warmest on record at 13.5 degrees. This is 0.77 degrees above the 20th century average.
  • Worldwide ocean surface temperature was the highest for any March on record at 0.56 degrees. The average sits around 15.9 degrees.
  • Global land surface temperature was 1.36 degrees above the average of 5.0 degrees -- which makes it the fourth ever highest recorded. Warmer than average temperatures affected Canada and South Asia. Meanwhile cooler than normals regions included Mexico, southeaster United States and northern and western Europe.
  • El Nino weakened in March, but contributed significantly to the warm tropical belt and overall ocean temperature.
  • The combined global land and ocean surface temperature was the fourth highest on record for January to March. It was 0.66 degrees higher than usual.
  • According to the Beijing Climate Centre, Tibet had it's second warmest March since calculations began in 1951. The India Meterological Department said that Delhi, India had it's second hottest March as well since calculation records began in 1901.
  • Arctic sea ice covered around 15.1 square kilometers in March. This is 4.1 percent below the average expanse and the smallest March coverage since records began in 1979. March tends to see maximum coverage of ice and this year marks the 17th consecutive March with below-average Arctic sea ice coverage.
  • The Xinjiang province had it's wettest March since 1951. Meanwhile, Guangxi and Hainan provinces in southern China experienced the driest March on record.
