WASHINGTON – APRIL 5: Rosario Ponte, of Alexandria, Virginia photographs the cherry tree blossoms that circle the Tidal Basin as the trees began to bloom April 5, 2005 in Washington. The National Cherry Blossom Festival — a celebration to commemorate the 1912 gift of 3,000 Yoshino cherry trees from Japan — will run until April 10. Originally from Venezuela, Ponte has been photographing the annual bloom for the past 30 years. She said it is her dream to be good enough to shoot photos for the National Geographic magazine.

WASHINGTON — Once again, fickle weather has changed the predicted bloom dates for D.C.’s cherry blossoms. National Park Service officials are now saying that the best time to see the blossoms is on March 23 and March 24.
[related_gallery align=”right”]This timeframe is narrower than the March 18-March 23 prediction park officials gave last week. National Park Service spokesman Mike Litterst said Tuesday that colder temperatures were the reason for the shorter bloom window.
“It’s really like nothing else we do, trying to predict something that so many people are counting on,” Litterst said last week.
This year’s National Cherry Blossom Festival, which marks the anniversary of Japan’s gift of 3,000 cherry trees, runs from March 20 through April 17. It’s one of D.C.’s biggest tourism events.
But peak bloom doesn’t always coincide with the festival’s dates. Peak bloom is when 70 percent of the trees around the Tidal Basin are in blossoming. Once in bloom, the flowers can last four to 10 days, depending on weather conditions.
Litterst says when the prediction is made more than a week in advance, it’s tricky to get it exactly right, especially as Mother Nature tends to change plans without warning in the spring.
The earliest the cherry blossoms have bloomed was on March 15 in 1990, Litterst says.
The revised peak bloom date is causing the park service to move up the opening of the Tidal Basin Welcome Area too. The area, located near the paddle boats at Maine Avenue SW and Raoul Wallenberg Place SW, will now be open from March 18 — April 3 (it was previously scheduled from April 2-17).
