? 4 days in mid to late March where the low temperature was warmest on record{ }

? High temperature of 105 degrees on July 7 came within a degree from the all-time record high in Washington of 106 degrees set on July 20, 1930

? Total precipitation was 32.45 inches, which is 7.29 inches below average for the year. Only 13 years have been drier than 2012 since records began in 1871.

? Although the official number can’t be tallied yet because the year is not over, 2012 will rank as the warmest ever in D.C. 1991 with an average annual temperature of 60.2 degrees will move to second place and 1990 and 1998 will be tied for third place at 60.0 degrees.
