How accurate is SurfSeer, actually?
The honest answer has three parts: what we can show you now, what we can't yet, and how you can check for yourself.
What we can show you
We publish a dated ledger of surf calls made the night before and graded the next morning against fixed rules. Hits and misses both. That's the only accuracy claim we're willing to make in public, because it's the only one you can audit.
The ledger covers three named breaks on the launch coast. It is a sample, not a universal claim — but it's a sample you can check line by line.
What we can't tell you yet
We can't give you a single accuracy percentage for every break on earth, and anyone who does is guessing. Break behaviour varies enormously, and a number averaged across all of them would be true of nowhere.
We also can't promise your break is dialled on day one. A spot sharpens as sessions get logged against it. Until then the app says so rather than pretending otherwise.
How to check us yourself
Log sessions. Rate each prediction over or under. The app shows you what it predicted against what you actually surfed, so your own record accumulates alongside ours.
If it's consistently wrong at your break, that's visible to you in the session history within a couple of weeks — no marketing required.
Where a prediction goes wrong
Rapidly shifting sandbanks, a wind change that arrives early, a swell with an unusual direction for the season — these are the conditions where any forecast, ours included, gets less reliable.
Predictions are guidance. Conditions change, and no forecast replaces your own read of the water when you're standing in front of it.
