April Fools’ Day weather?

 

An April day along the C&O Canal

April is a dynamic weather month in the nation’s capital that can sometimes feature chilly March-like weather. However, summer-like warmth can also occur with highs in the 80s and 90s. 

Average daily high/low temperatures in the nation’s capital range from 62°/43° on April 1 to 73°/53° by April 30. DC’s hottest April temperature of 95° occurred most recently on April 17, 2002. That’s compared to DC’s coldest April temperature of 15° on April 1, 1923. Weather records in the nation’s capital date back to 1871.  

The nation’s capital had 11 warmer than average April’s over the last two decades. April 2017 and April 2019 were DC’s warmest and second warmest on record. Sandwiched in between was April 2018, which finished as DC’s coolest since 1997. That helps illustrate how changeable DC’s spring weather can be from one year to the next.

Washington, D.C. averages 3.21” of April rainfall, according to NOAA. The nation’s capital has seen a high degree of variability in April rainfall in recent years. While April 2020 ranks among DC’s wettest, last April was unusually dry with only 2.06” of rain. 

While showers and thunderstorms become more common as spring wears on, they can occur at any point in April. Showers and storms return to the forecast tomorrow afternoon for the nation’s capital and surrounding suburbs. However, it isn’t expected to be as large a severe weather event as on April 6, 2017, when two tornadoes touched down within DC city limits. Meanwhile, the latest in the spring that measurable snowfall has occurred in the nation’s capital was April 28, 1898 (0.5”).

NOAA's Climate Prediction Center expects this month to finish with near average temperatures and rainfall. That would be in contrast to April 2024 which was DC’s third warmest. It also follows DC’s fourth warmest March that was also drier than average. Eight of the last 12 months have also been drier than average in Washington, D.C. That’s led to severe drought conditions across the DMV, so any rainfall would be beneficial.

DC’s March 2025 weather keeps rare company

 

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 29^th (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.
