Will the 2023 peak blossom of cherry trees in Kyoto happen before April 5th?
resolved Mar 27

There is a competition to predict date of cherry blossoms across the world:

https://competition.statistics.gmu.edu/ so lets do a Manifold attempt.

Market will resolve the date using the same technique as the competition: The peak bloom date of the Prunus jamasakura is determined by a local news paper in Arashiyama (Kyoto, JP). Will resolve YES if peak blossom is April 4th or earlier, otherwise will resolve NO.

The last few peak blossom dates are: 2019-04-05, 2020-04-01, 2021-03-26 (this was the earliest ever), 2022-04-01

Clear reports of full bloom already happening in Kyoto from multiple sources - there might be some discussion on the exact date, but this can safely resolve "YES" https://tenki.jp/sakura/expectation/
