Okinawa Dive Watch

Okinawa Dive Watch is the fastest way to know if today is a good day to dive.

Built for divers, instructors, and dive shops across Okinawa — from Maeda's Blue Cave to Cape Zanpa, Motobu, Kerama, Naha, and the southern reefs — Dive Watch pulls live ocean and weather data straight to your phone so you stop guessing and start diving.

WHAT YOU GET • Real-time wind speed, gusts, and direction at every major dive site • Live wave height, swell period, and direction from marine forecast models • Sea surface temperature and air temperature • Tide charts with high/low times for each region • Live HD webcams pointed at popular entry points (Maeda, Onna, Motobu, Naha, Zanpa) • A simple go / caution / no-go score per site, calculated from current conditions • Forecast view so you can plan tomorrow's dive, not just today's

WHY IT EXISTS Conditions on the East China Sea and Pacific sides of Okinawa can flip in hours. A site that's glassy at sunrise can be 2-meter swell by lunch. Dive Watch consolidates the data that local guides already check across five different websites — wind, swell, tide, webcam, sea temp — into one screen, refreshed live.

WHO IT'S FOR • Recreational divers visiting Okinawa • Local instructors and dive masters checking morning conditions • Dive shop owners deciding whether to run a charter • Snorkelers, freedivers, and spearfishers • Military divers stationed on Okinawa

No ads. No paywalls on conditions data. Just a fast, focused tool that respects your time and your safety.

Data sources: Open-Meteo weather and marine APIs, WorldTides, and partnered live webcam feeds. Site database curated locally in Okinawa.

Dive smart. Dive Okinawa.
