About & terms

Free, independent and non-commercial

Folly Surf is a free, non-commercial project using publicly available environmental data and licensed services. Our rating formula is openly published. Source data and camera imagery remain subject to their providers’ licences and attribution requirements.

Information, not a promise

Everything here is for general information. Forecasts, camera views and ratings may be delayed, incomplete or wrong. The Folly Index is an experimental formula, not a locally validated prediction or a safety rating. It cannot assess your ability, changing sandbars, currents or conditions at the water.

We cannot promise a barrel, a good session or a safe one. Surfing, swimming, travel and all other activities are undertaken at your own risk. Check official warnings, follow lifeguard instructions and use your own judgment.

The site is provided “as is” and “as available”, without warranties of accuracy, availability or fitness for a particular purpose. To the extent permitted by applicable law, Folly Surf and its contributors accept no responsibility for injury, death, loss, damage or other consequences arising from use of, or reliance on, this site. Nothing here excludes liability or rights that cannot legally be excluded.
