International Cherry Blossom Prediction Competition

2024 Prediction Competition

When will the cherry trees bloom in 2024?

We invite contestants to submit their predictions for Washington, D.C. (USA), Kyoto (Japan), Liestal-Weideli (Switzerland), Vancouver, BC (Canada) and New York City (USA), along with a compelling narrative and reproducible analysis containing any data and code used. Complete entries will be eligible to win cash and prizes—based on multiple categories, including best prediction and best narrative—and will be featured on Real World Data Science. See the complete competition rules for details.

The 2024 competition is now closed.

Submissions were accepted until Feb 29, 2024.

Check out the entries of the past winners to get some inspirations on successful modeling techniques and narratives. The “getting started” videos provide information on cherry trees, bloom dates, and how to start modeling. In addition, see this template GitHub repository and the tutorial on the The Law of the Flowering Plants.

Please contact the competition organizers with any questions using the contact submission form.
