Try your hand at building a model by choosing a few beaches in the box below. The more beaches you choose, the more expensive your model becomes. Our model uses five beaches and scores about 38% on accuracy. Can you do any better?
Once you press the Build Model button, you'll see results and a map showing how you did on individual beaches. You can also adjust the false alarm rate, or days when unncessary warnings were issued. To compete with our model, keep it below 2%.
