About this app

Know before you go. AI-powered marine weather, tides, and waves for your exact spot and time — plus fishing forecasts, GPS tracking, and live ocean maps.

SeaLegs AI is built for boaters, sailors, cruisers, and anglers who want a sharper forecast than a generic weather app and a clearer plan than a stack of satellite tabs. One app, four tools.

🌊 WHO IT'S FOR
Day-trippers, sandbar regulars, and weekend cruisers picking beach days, harbor hops, ICW legs, and marina-to-marina runs with family aboard. Sailors on coastal passages, overnight hops, gunkholing, and bluewater crossings — reading wind, swell, and the windows between systems. Offshore anglers trolling, jigging, chunking, bottom fishing, kite fishing, and daytime swordfishing the canyons, ledges, and thermal breaks. Power boats, sailboats, catamarans, sport fishers, yachts, and trawlers.

🌤️ MARINE WEATHER
AI-powered marine forecasts for your route and departure — a beach day, a coastal passage, or a run offshore. We aggregate ECMWF, GFS, and ICON — three of the top global weather models — then translate thousands of wind, wave, swell, and gust data points into one plain-English read.

🎣 FISHING REPORTS
AI fishing forecasts for a chosen area and date. Reads sea surface temperature, chlorophyll, currents, and bathymetry — the same data offshore pros pay subscriptions to interpret — then highlights the top spots with a plain-English write-up on why they're fishing now.

Fishing Reports are available in the U.S., Canada, Mexico, the Caribbean, Central America, the northern coast of South America, Brazil, the Mediterranean, the Arabian Sea, Australia, and New Zealand. Coverage expanding.

📍 GPS TRACKER
Real-time tracking with condition alerts, inshore or offshore — a beach run, a coastal hop, a troll offshore. SeaLegs watches for weather changes that could affect your run home. Push notifications when a shift matters — silent when it doesn't.

🗺️ OCEAN MAPS
Live ocean-data map layers: sea surface temperature (SST), chlorophyll (CHL), bathymetry, thermocline, ocean currents, eddies, and thermal fronts. Read the water the way a captain does — temperature breaks, color edges, depth contours, the layer fish hold under, the current seams that carry bait, eddies that pile bait against themselves, and the sharp thermal fronts that concentrate life along their edges. Ocean Maps cover the same regions as Fishing Reports — coverage expanding.

HOW IT WORKS
1. Plan. Drop a pin on your destination, pick a departure time, and tell us about your boat.
2. Analyze. The AI reads weather and ocean data for your specific route and area — not a regional average.
3. Decide. Get a simple Go / Caution / Avoid recommendation, with hourly detail and alternate timing if today is marginal.
4. Share. Send any forecast or fishing report to your crew as a link. They can open it in the app or a browser, and it updates when you refresh it.

WHY SEALEGS AI
No subscription traps. Marine weather, GPS tracking, and ocean maps are free to use where available. Fishing Reports are pay-per-report — pay when you need one, skip when you don't.

Built by boaters. Tested offshore. Updated every release with the features captains ask for.

Ratings and reviews

As a fishing guide I depend on various weather apps to determine potential destinations for trips. Sea Legs is among the best apps I have found. It allows you to input where you want to go, departure time, and return time. It calculates the conditions you will be encountering throughout and updates accordingly up to the time of your trip. Is it perfect? Nope. But it's far better than most. And beats relying on the weatherman who are wrong more often than not. If you fish, this app is worth it!

still testing but highly enjoying it. I've compared my normal weather planning methods and this and it gives a very similar and comprehensive overview. I also like that it teaches/exposes me to different types of statistical analysis and variables which I personally enjoy (e.g., wave power). it now forms my first step for every trip and will be the first step for everyone that asks me "how's the weather looking for XYZ?" Cool tool! excited to use and see more. works great on low bandwidth con

SeaLegs AI provides very useful fishing data for Pakistan and the Arabian Sea. Excellent chlorophyll maps and ocean intelligence tools.
