The 2009 “Snowpocalypse” buried the region under up to two feet of snow, setting a December storm record and delivering D.C.’s most recent white Christmas.
A relatively modest 65-degree record high—set in 2021 and tied in 2024—stands as December’s lowest daily record, making it one of the easiest marks to break during mild spells.
A light 2010 snowfall marked the season’s first accumulation after the record snowy winter, though it still managed to snarl travel despite modest totals.
A record 2.55 inches of rain in 2018 helped push the year to its wettest on record, part of an exceptionally soggy stretch with frequent heavy downpours.
A heavy 1966 snowfall dumped nearly 7 inches of slush and kicked off a notably snowy December, while in 2015 the same date saw record warmth in the 70s during the city’s warmest December on record.
A record 1.29 inches of rain in 2009 helped fuel one of the wettest Decembers on record, boosted further by the moisture from Snowpocalypse later that month.
