About Sea Window: Marine Weather

Find your weather window. Sea Window shows the forecast at every point of your trip, timed to when you'll actually be there, and ranks the best times to leave over the next three days. Built for coastal sailors, cruisers and anglers whose trips are long enough for the weather to change on the way. WEATHER AT EVERY WAYPOINT, WHEN YOU GET THERE Set a route and your boat speed. Sea Window times the forecast to your arrival at each waypoint: wind and gusts, seas with the period next to the height (3 ft @ 8 s), tide, visibility and rain, on one timeline. See what it's like when you get there, and what the ride home looks like. THE BEST TIMES TO LEAVE, RANKED The Departure Advisor scores every departure over the next 72 hours for your whole trip, not just the hour you cast off, and tells you why: wind, seas and visibility along the way. IF THE MODELS ALIGN, YOU'LL KNOW A model-agreement badge…
