It's still too early to guess with much confidence when the 2023 bloom will be. But we've seen a much-warmer-than-normal January, and long-range forecasts suggest above-average temperatures continuing as we get deeper into February (after a short very cold spurt at the beginning of the month).
On average, Washington DC's cherry blossoms bloom around late-March into early April, but the precise timing varies year to year depending on the local temperatures in the leadup to the bloom. You can find general information on the 2023 bloom to help plan your visit here.
On March 6, two days after the National Park Service issued their peak bloom date prediction, the Washington Post‘s Capital Weather Gang issued their own prediction of a peak bloom on April 9 (or, as they put it: “most likely between April 7 and April 11, centered on April 9”.)
With March having been colder than they expected, they've now pushed back their prediction to April 13 (or, as they now put it: “between April 11 and April 15, centered on April 13”).
