And for Washington, DC: April 8-12

Seems late. The so-called "indicator tree" is in full bloom. I am told that this usually means the rest will reach peak in about 7=10 days.

Just in time for easter which is when I go to D.C.

Interesting! I didn't know about the indicator tree.

This is a specific use of phenology, studying animal/plant life cycle events, like flowering time.

Since ancient times, people have noticed these events – the first snowdrops show spring, for example – and in the 19th century, some naturalist-nerds started recording the exact dates. This was then a surprise climate change dataset.

Thanks for sharing! I've been following a bunch of car enthusiasts from Japan on Instagram, and the past week or so they've begun posting photos of the cherry blossoms. Very cool to visualize the actual progression with a map (since I don't know many of the mentioned areas in the posts, usually).

Why aren’t any blossoms shown in Hokkaido?

Probably because it's too cold there?

They bloom later there because of the weather, but they still bloom.
