How accurate is SurfSeer?

We publish forecasts for three named spots the night before, and check them the next morning against fixed rules. Correct and wrong results are both kept. This is the only accuracy claim we make, because you can check it.

It is a sample of three spots, not a claim about every spot.

There is no single accuracy figure for every spot. Spots behave very differently, and an average across all of them would not describe any one of them.

Predictions for a new spot improve as sessions are logged there. The app shows how many sessions a spot's predictions are based on.

Log your sessions and record how the waves compared with the prediction. The app shows predicted and actual conditions side by side.

If predictions are consistently wrong at a spot, you will see it in your session history within a few weeks.

Fast-changing sandbanks, wind changes that arrive early, and swell from an unusual direction all make any forecast less reliable, including ours.

Predictions are estimates. Always check the water yourself before you go in.
