March 2025 will finish as one of DC’s warmest on record. The frequency of warmer than average weather has far exceeded cooler than average weather over the course of the month.
An eye-popping 25 of the first 29 days of March featured above average temperatures in the nation’s capital. DC’s warmest March temperature occurred on the 29th (86 degrees). This was DC’s first 80-degree day since November 7, 2024 (84 degrees). Not since September 10, 2024 had it been warmer in the nation’s capital (87 degrees).
By comparison, DC’s coldest temperature this month of 23 degrees occurred on March 2. No more than two consecutive colder than average days were observed this month (March 2-3 and March 26-27). The warmer than average weather led the National Park Service to declare peak bloom of the cherry blossoms along the Tidal Basin on March 28.
Highs both today and tomorrow will be either side 80 degrees in the nation’s capital and will coincide with the potential for showers and storms on March 31. Since the month has been much drier than average to this point, 1.49” vs. a March average of 3.50", it’s a near certainty that the month will finish as a drier than average month.
DC’s average monthly temperature (combining daily high/low temperatures) of 52.9 degrees through March 29, will help this month rank among DC’s Top 10 warmest on record. Including this month, five of DC’s 10 warmest March’s have occurred since 2012.
