Cherry blossom season has arrived in Washington, D.C., where pink and white flowers dot thousands of trees around the city as this year's peak bloom approaches. To celebrate the iconic springtime sight, locals and tourists alike can participate in the National Cherry Blossom Festival, an annual event series that runs for four weeks and features a mix of art, music, food and more. Originally a gift from Japan to the United States, the capital's cherry blossoms appear along the Tidal Basin and in parks near several of the capital's monuments and memorials.

The National Park Service determines the cherry blossoms' "peak bloom" date by predicting when 70% of the blossoms on the Yoshino cherry trees, which are the most common type of cherry tree planted along the Tidal Basin, will be open.

Typically, peak bloom occurs between the last week of March and the first week of April, according to the park service, which notes that forecasting the peak is impossible to do more than 10 days ahead of time. The average peak bloom date falls on April 3, according to the Environmental Protection Agency, which similarly advises that the exact timing varies from year to year because warmer temperatures can encourage an earlier bloom.
