Last month was the sixth-wettest October on record in Baltimore, with 7.62 inches of rain measured at Baltimore-Washington International Thurgood Marshall Airport.

The bulk of it, 6.01 inches, fell over two days, the 10th and the 11th. It means that half of the six wettest Octobers on record have occurred within less than a decade, with 8.92 inches last year (largely from Hurricane Sandy) and 9.23 inches in 2005 as the top two.

Rainfall has been above normal in seven out of the past 10 months of October at BWI. On average, 3.33 inches of rain falls over the month.

The average temperature at BWI was meanwhile 58.8 degrees, about 2 degrees above normal and the warmest for October since 2007. Though the month ended with a string of days slightly cooler than normal, that was not enough to outweigh six consecutive days that topped 80 degrees -- including one that hit 90 degrees -- to start the month.

It was a second consecutive October in which no snowfall was measured at BWI. A trace of snow was last measured in October 2012, and before that October 2003.
