Not only was it the hottest March on record for the U.S., but the amount it was above normal beat any other month in history for the Lower 48 states. March’s average temperature of 50.85 degrees Fahrenheit (10.47 degrees Celsius) was 9.35 F (5.19 C) above the 20th century normal for March. That easily passed the old record of 8.9 F (4.9 C) set in March 2012 as the most abnormally hot month on record — regardless of the month of the year — according to records released Wednesday by the National Oceanic and Atmospheric Administration.

The average maximum temperature for March was especially high at 11.4 F (6.3 C) above the 20th century average and was almost a degree warmer than the average daytime high for April, NOAA said.

Six of the nation’s top 10 most abnormally hot months have been in the last 10 years. This February, which was 6.57 F (3.65 C) above 20th century normal, was the tenth highest above normal.

“What we experienced in March across the United States was unprecedented,” said Climate Central meteorologist Shel Winkley. “One reason that’s so concerning is just the sheer volume of records, all-time records that were set and broken during that time period. But also this is coming on the heels of what was the worst snow year. And the hottest winter of record. So we’re seeing this continuation of extraordinary heat that took place during the winter months, continuing into the spring months as well. That’s where it’s really concerning, it’s just the duration of this heat.”

More than 19,800 daily temperature records were broken for heat across the country, according to meteorologist Guy Walton, who analyzes NOAA data.
