About The Buoy
The Buoy modernizes access to marine wave buoy data by offering you a smooth and fast mobile experience. The app allows you to check essential real-time conditions: wave height, period, energy and wind.
By combining buoy observations with forecasts based on reliable weather models, The Buoy allows you to analyze both the current state of the water and its expected evolution.
Launched from Biarritz, The Buoy is a project by Thomas Cailhol, a developer and surf enthusiast in the Basque Country. The app integrates data for France (including overseas territories), Spain, United Kingdom, Ireland and Portugal.
Reliable data sources
The Buoy aggregates data from official organizations and recognized weather models to provide you with accurate and up-to-date information.
