September D.C. outlook: Another rainy month, but with near normal temperatures
Ida to ignite a wet start to the autumn months.
Let’s start this story with some good news. After more than half of August delivered days with highs in the 90s, we have a reasonable chance to see no temperatures this hot for at least the first half of September. As longtime Washingtonians know, the early half of September can still deliver significant summer heat and humidity, so this is a welcome break from the recent steamy conditions.
Our outlook for September calls for near-normal temperatures and above-normal rainfall. The 30-year average temperature for September is 72.4 degrees, with an average high of about 81 and low of 64. We expect this September to average between 71 and 74 degrees.
Average September rainfall in Washington is 3.93 inches and, thanks to the remnants of Ida passing on the month’s first day, we may make it halfway there after just 24 hours. Our current thinking is that we’ll see four to six inches for the month. While wet, this is still well below the nine-plus inches we’ve seen this August.
