Assessing the U.S. Climate in March 2017

Map of March 2017 U.S. average temperature percentiles

During March, the average contiguous U.S. temperature was 46.2°F, 4.7°F above the 20th century average. Record and near-record warmth spanned the West and Great Plains, with below-average temperatures in the Northeast. The year-to-date contiguous U.S. average temperature was 40.3°F, 5.1°F above average. This was the second warmest January–March on record, behind the record of 41.4°F set in 2012.

The March precipitation total was 2.56 inches, 0.05 inch above the 20th century average, and ranked near the middle of the 123-year period of record. Much-above-average precipitation across the Northwest offset much-below-average precipitation in the Southeast. Warm and windy conditions across the South created ideal wildfire conditions with over 2 million acres burning during March—a new record for the month. The year-to-date contiguous U.S. precipitation total was 8.09 inches, 1.13 inches above average. This ranked as the 10th wettest January–March on record and wettest since 1998.
