Washington, D.C. ties record for most 95 degree or hotter days

At 2 p.m., the mercury met the 95-degree threshold for the 28th time this year in Washington, D.C., matching the record for the most such days set in 1980. 2012 leaves behind 2010 and 1991 tied for second place with 27 95+ days.

Today also marks the 50th time the temperature has hit at least 90 this year. D.C. has now had at least 50 90+ days in three consecutive years, for the first time on record. In 2010, 67 90+ days were logged (tying 1980 for the most on record) and there were 50 such days in 2011.

These most recent records add to a stunning list of heat milestones we’ve established over the last three summers documented in July, including the most consecutive set of days at 95 or higher, 11, June 28-July 8.
