Wind Over Water
Marine winds behave differently than on land. Get accurate open-water wind speed and gust forecasts built from marine-specific models.
Multi-Model Forecasting
SeaLegs AI compares multiple professional weather models to find where they agree and where they diverge, so you get the most reliable marine forecast.

What Users Are Saying
From real App Store reviews
"In short this app is nothing short of exceptional, with nothing like it available. I've only been using it for a few days, but so far it has been absolutely on point. It's definitely an extremely useful tool to have in your tool box of boating apps."
"Really like that it automates a lot of the cross checking I have to do with other weather apps (different models, wave height/wave period). Less likely I miss something. It does comfort/safety really well."
"A very useful and complete app, easy to use right from the start. I highly recommend it! Safe boating to everyone."
