Surfline's
LOLA Swell Model is the ONLY global swell model that can separate individual swells to accurately calculate surf heights for any location on Earth. Every surf spot will only have a limited range of swells that produce good surf at that location. Compare the LOLA swell forecast with a spot's "Optimal Conditions" information and your own local knowledge to score the best surf.
The "Swell Rose" above is the only one of it's kind in the world. This shows the directions of all the incoming swells (N=0° East=90° etc). If you mouse over the swell rose you can see detailed raw numbers of the underlying swells.
US Weather data comes from the
WeatherUnderground array of personal weather stations. Data is near realtime. International weather comes from LOLAs high resolution models or WUG where possible.
Tides are generated using the most excellent
Xtide system.
