Key features: • Surf forecast & scoring — a 10-day outlook with an easy 1–5 rating for every spot, tuned to each break's swell window, tide preference, and bottom type • Best Surf ranking — see which spots are firing right now, sorted across the whole island • Tide & moon — tide charts and moon phase together, so you know exactly when the window opens • Live cams — check real-time video before you drive out • Typhoon tracking — official CWA typhoon and marine warnings, plus swell forecasts through typhoon swell events • Pocket Spots — save your go-to breaks for one-tap access • Surf Alerts — get notified when your saved spots hit the conditions you're after • Multi-source forecast data from ECMWF, NOAA, DWD, Météo-France, and Taiwan's CWA SwellLab Pro unlocks the full 10-day forecast at our most advanced spots, hourly data refresh, unlimited Pocket Spots and Surf Alerts, and the full Best Surf ranking beyond today.

  • This app hasn’t received enough ratings or reviews to display an overview.

• Wind gusts now count toward spot scores Scoring used to look at average wind speed only. Gusty hours — light on average but punchy in the gusts — now score lower and say so, reflecting the chopped-up face you actually paddle out into. • Scoring fixes for west and southwest coast spots Per-spot wave height curves tightened, and Mashagou's swell window is now measured against the true coastline normal. • Forecast sample points moved inshore at three spots They were sitting too far offshore. Wave height and wind now match what's happening at the beach. • Simpler Stories tabs Just Latest and Regions now — open it and you're on today's newest posts.
