Warm pattern resumed in June
We're a bit late here taking a look back at the weather for Baltimore during the past month. Just threw out the last wedding guests.
After a cool and very wet May, June at BWI resumed the warm pattern that has prevailed here since the beginning of the year. Temperatures at the airport averaged 75.3 degrees last month. That was 3.5 degrees above the long-term average of 71.8 degrees, and made it the warmest June since 1994, and the fourth-warmest in Baltimore in 65 years.
1943: 79.8 degrees
1994: 77.2 degrees
1949: 75.6 degrees
2008: 75.3 degrees
So far this year, only May ended cooler than the norm.
Precipitation was close to the June average for BWI, at 3.70 inches. The long-term average is 3.43 inches. Ten days saw measurable rainfall.
The high temperature for the month was 96 degrees, on the 10th. The low was 52 degrees, on June 18. No new records were set.
Not unexpectedly, given the warm temperatures, we ran well ahead on cooling degree-days, a measure of the demand for energy for cooling. We were up 34 percent over the average for June.
Looking ahead, July is typically our hottest month, with average temperatures peaking third week in the high 80s. The all-time record high temperature for Baltimore is 107 degrees, set on July 10, 1936. Only 7 dates have record highs of less than 100 degrees.
The coolest record daily high for the month (and therefore the easiest record to break) is 97 degrees, set on July 12, 1908 and July 24, 1987.
The record low for the month in Baltimore is 50 degrees, set on July 1, 1988 and again on July 3, 2001. The warmest record low is 59 degrees, set July 19, 1962.
The wettest July on record for Baltimore was in 1889, when 11.03 inches fell. The driest was in 1955, with just 0.3 inches in the gauge.
