The thermometer of record never reached triple digits in Baltimore in July, the first time that has occurred since July 2009.
The month topped out at 97 degrees at BWI Marshall Airport on July 18, and hit the 90s nine times. That is below the norm of a dozen 90+ degree days here in July, which is on average the hottest month of the year.
While triple-digit temperatures have seemed like a typical occurrence in recent summers, they aren't all that common. They have been recorded in 47 of the 141 years on record for Baltimore, according to Washington, D.C., researcher Ian Livingston's blog (Livingston also contributes to the Washington Post's Capital Weather Gang blog).
That includes five years out of the past decade.
The average temperature at BWI was 79 degrees in July, which is also the coolest since 2009. But it is still above-average for the month. Each of the past three years topped 81 degrees in July, on average, while a typical July in Baltimore averages 77 degrees.
Of course, while BWI did not climb out of the 90s, the Inner Harbor did. The airport has been the point of record for Baltimore since opening in 1950.
