Climate reports are in for the month of March for the U.S. and Globally. Although it was cool across the U.S., it was warm globally.

One year after March 2012, which featured a temperature departure at DCA (Reagan National Airport) of +10 degrees, there was a stark contrast with not only D.C., but the majority of the United States experiencing below average temperatures. March 2013 featured temperatures of 0.9 degrees F below the 20th century average. This included a -3 degree F temperature departure locally at DCA. March across the U.S. was the coolest in over 10 years.

Global temperatures were a different story as they registered as the 10th warmest on record. Where was it warmer than average last month you ask? Take a look at the graphic below produced by NOAA's National Cimatic Data Center (NCDC).

In North America, portions of eastern Canada to Greenland experienced much warmer than average temperatures due to the blocking pattern which kept the U.S. cool. Africa, the Middle East and most of Asia recorded warmer than average temperatures as well as Austrailia. Cooler than normal temperatures were in place across Siberia as well as the majority of Europe.
