2019 will end as one of Baltimore’s mildest years on record.

Temperatures averaged 58 degrees across the year at Baltimore-Washington International Thurgood Marshall Airport, about 2 degrees warmer than normal. That ranks it as 10th-warmest in a record book that goes back to 1872.


There were 59 days at 90 degrees or hotter at BWI, more than twice the region’s average of 28 days in the 90s per year. That ties a record set in 2010, and is five more days in the 90s than in 1988, the year with the next most frequent heat.

January, March and November were the only months of the year with below-average temperatures at BWI.

2019 was meanwhile one of the region’s driest years of the decade. A year after setting a record for precipitation — 71.82 inches at BWI — rain and snow at the region’s point of record was little more than half that, at 38.13 inches.

It is the third time this decade that less than 40 inches of precipitation fell across the region, and Baltimore’s driest year since 2012, when precipitation totaled 37.42 inches. Average annual precipitation in Baltimore is about 42.6 inches.

The year included extremes ranging from 100-degree highs to a 5-degree low, as much as 1.47 inches of rain in a day, and as many as 12 days in a row without rain.
