Big Buoy puts live marine conditions in front of you before you fish. Real NOAA buoy data, tides, solunar tables, wind and wave forecasts. The stuff that decides whether you go and where you set up. LIVE NOAA BUOYS 873 stations across the East Coast, Gulf, Great Lakes, and West Coast, updated every 10 minutes. Water temp, wave height, swell period, wind speed and direction. Straight from the buoy, no fluff. TIDES THAT DON'T GO DOWN Tide predictions for 3,400+ stations, served from Big Buoy's own servers. When government feeds have an outage, your tides keep loading. Charts show highs, lows, and the current stage at a glance, and the gauge picker always shows the closest station to you with live status. DEPTH CHART (PRO) Survey-grade bathymetry built from NOAA ENC and Army Corps eHydro surveys, layered right on the map. Read the bottom. Find the ledges, humps, channels, and drop-offs that hold fish, inshore and offshore. SOLUNAR FISHING TIMES Major and minor feeding windows computed with a real astronomical model, tied to your spot. Plan the day around the bite instead of the other way around. WIND, WAVES & WEATHER 7-day forecasts free, 16 days with Pro. Pro also compares all five major models (GFS, HRRR, ECMWF, GEM, ICON) so you can fish the consensus instead of trusting one run. SAVED SPOTS & MONDAY BRIEFING Save unlimited spots. Get a Monday morning email that reads the week ahead for your water so you can pick your day early. BIG BUOY PRO For anglers who fish around a work schedule. Limited days on the water means every trip has to count. Pro gives you the 16-day window, every forecast model, the Depth Chart, and satellite overlays (sea surface temperature, chlorophyll, ocean currents) to pick the right day and run straight to fish. Ad-free. $4.99/month or $39.99/year. The free tier stays genuinely useful: live buoys, 7-day forecasts, tides, and solunar, supported by ads. REAL DATA, REAL SOURCES NOAA NDBC buoys. NOAA CO-OPS tide predictions. NOAA ENC and USACE eHydro surveys. Copernicus satellite data. We show you where every number comes from.
