July was the hottest in 118 years in the continental U.S., and the nation marked its warmest 12-month period for the fourth month in a row, according to a report released Wednesday.
It was the third-hottest month of July for Maryland. The month was previously reported to be the fifth-hottest July on record for Baltimore.
The average temperature for the contiguous states was 77.6 degrees last month. That is 3.3 degrees above the average July temperature over the 20th century and two-tenths of a degree hotter than the previous record, set during the Dust Bowl years in 1936.
Over the 12 months from August 2011 through July 2012, the continental U.S. averaged 56.1 degrees, again raising a record. Every month since April has marked the warmest 12-month period on record for the contiguous states.
The figures are according to State of the Climate, a monthly report released by the National Climatic Data Center.
