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.
The Washington Post‘s Capital Weather Gang have issued their first peak bloom forecast for the season: “most likely between April 7 and April 11, centered on April 9.”
That's very similar to the National Park Service forecast of sometime between April 8 and 12.
Last year the Capital Weather Gang's forecast ended up being closer than the initial NPS forecast, although it was still a few days on the early side.
