SwellLab

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:

• Localized surf ratings: individually calibrated for each spot based on its break characteristics, swell window, wind direction, and tide conditions • 10-day forecasts: view wave height, period, swell direction, wind speed and direction, tides, sunrise, and sunset in one place • Nearby spots: compare surrounding conditions, sorted by distance • Pocket Spots: save your regular surf spots and check the latest conditions at a glance • Typhoon and marine alerts: official warnings from Taiwan’s Central Weather Administration displayed directly on affected spots • Bilingual interface in English and Traditional Chinese

Forecast data combines global numerical weather prediction models from NOAA, the European Centre for Medium-Range Weather Forecasts (ECMWF), the German Weather Service (DWD), and others through Open-Meteo. It also incorporates official observations and weather alerts from Taiwan’s Central Weather Administration (CWA), along with astronomical data from NASA.

Forecasts are for reference only. Always assess current conditions and your own ability before entering the water.
