About

SwellLab is a surf forecast app built for surfers in Taiwan. Covering 40+ surf spots across the island, it turns wave height, period, swell direction, wind, and tides into easy-to-understand localized ratings — helping you quickly decide where to surf and when to paddle out. 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. Early-bird pricing available for a limited time.
