Live wave heights on every ocean, real NOAA buoys on top, and verified reports from people standing at the water. Refreshed hourly. No accounts, no ads.
Some apps show you forecasts. Swellwise treats the ocean like the main attraction.
A live wave-height map covers every ocean on Earth — the same NOAA physics model the big surf sites run on, refreshed every hour with the estimate that's valid right now. Tap any patch of water and get the full picture: combined height, period and direction, wind, and every individual swell train, from long-period groundswell to local wind chop.
Real NOAA buoys are drawn right on the map as ground truth. Tap one for live observations — wave height, period, water temperature, wind, and the observed swell split — with a three-day interactive history that keeps refreshing while you watch.
Then there's the part no model can give you: eyes on the water. Anyone at the coast can log what the waves are actually like — glassy, hollow, blown out, crowded — in ten seconds, anonymously. Reports can only be submitted from the water's edge, which is what keeps them honest. Each report carries the weather at that moment and stays on the map for 24 hours. Your own reports live in your private logbook forever.
WHAT YOU GET
- Global wave-height map, updated hourly from NOAA GFS-Wave
- Tap-anywhere breakdowns: height, period, direction, wind, swell trains
- Live NOAA/NDBC buoy stations with 3-day interactive charts
- Animated wind flow over the water
- Anonymous, location-verified wave reports with weather stamps
- "Near you" cards: closest waters and buoys, with distance
- Share cards for any spot, buoy, or your map view
- Private logbook of everything you've reported
WHAT YOU DON'T GET
No accounts. No ads. No trackers. No subscription — pay once and it's yours.
Your exact location is used only to center the map and verify you're at the water when you report; it's never stored or shown to anyone. Reports appear as a hazy area, not a pin on your spot.
Built for surfers, anglers, paddlers, sailors, and anyone whose day starts with "what's the ocean doing?"
Swellwise is for recreation, not navigation. For official marine warnings, consult NOAA/NWS marine products.
Water for the Wise.
