National Park Service officials say the Tuesday and Wednesday will be the best days to visit the cherry blossoms this year.
That is when the flowering trees ringing the Tidal Basin are expected to be at their peak.
Tourists and locals visiting the cherry blossoms Monday seemed to enjoy what they are seeing.
"They are at just about peak. It's lovely," says a woman from Vermont.
"They're just beautiful. And it's a beautiful day," says Bethesda's Kelly Lawrence, who brought her 4-month-old son, Ford, downtown.
An up-close look shows you what's happening: some buds are open. Others just about to burst.
"This is the best time of year in D.C.," says Daniel Lippman, originally from Great Barrington, Mass. "To see the blossoms, and it's not too hot out. It's not too cold. So it's just a perfect mix of everything that makes a nice afternoon."
Many in the crowd work downtown and come over during lunch.
"I was just noticing walking around the Tidal Basin," says Zina Watkins, who works at the U.S. Department of Education. "You're hearing all these international languages. It's a great time to get out and celebrate spring. It's just a wonderful time."
