Buoy Map puts live NOAA National Data Buoy Center (NDBC) observations on a worldwide map of ocean and lake stations. Tap a buoy to see what that station is actually reporting right now. Conditions typically update about every 30 minutes, depending on the station. WHAT YOU GET • Interactive map of NOAA / NDBC buoys around the world • Opens near your location on first launch • Remembers your last map view, including pan and zoom • Keeps the last loaded map if you lose signal, so you can still check what you already loaded when offline • 72-hour wave height graph when the station reports wave data • Light and dark map themes BUOY DATA Each station has a different set of instruments, so not every buoy reports every field. When the data is there, Buoy Map can show: • Wind direction, speed, and gusts • Wave height, dominant period, average period, and wave direction • Air pressure and pressure trend • Air temperature and water temperature • 72-hour wave height graph WHO IT’S FOR Surfers, sailors, fishers, paddlers, and anyone who wants a quick look at real water conditions before heading out or while already on the water. No account. No feed of extra forecasts mixed in. Just the buoy map and the observations. CREDITS Map tiles: OpenStreetMap. Map engine: Leaflet. Suggestions are welcome. I plan to keep improving Buoy Map, enjoy!

Verdict

The call

Buoy Map and Seagull Coast both sit at 5.0 stars, but that hides the real split: 100% of Seagull Coast's written reviews are positive against 33% of Buoy Map's. Seagull Coast also leads on price (Free vs $1.99) and update cadence (fortnightly vs every 5 months). On rating, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Buoy Map holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Seagull Coast has 428 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of Buoy Map's written reviews are positive against 100% of Seagull Coast's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Buoy Map ships an update every 5 months, Seagull Coast fortnightly. The most recent releases landed on October 9, 2026 and October 25, 2026 respectively.
