SeaState

v1.3.0: A premium redesign with a living ocean interface, a beautifully rebuilt Apple Watch app, and a smoother, faster SeaState everywhere.

Every ocean on Earth. Every condition that matters. SeaState is the marine weather app built for people who take the water seriously.

Whether you're crossing a channel, timing the surf, dropping anchor in a cove, or fishing offshore, SeaState puts swell height, wind speed, tides, currents, and weather in one place — updated live, for any coastline on the planet.

PIN ANYWHERE. COMPARE ANYTHING.

SeaState's signature side-by-side view lets you drop two pins anywhere on Earth and compare conditions live. Check the windward and leeward sides of an island at once. Scout two anchorages before you commit. See exactly how conditions differ across a few miles of water — a capability no other marine app delivers in a single screen.

WORLDWIDE COVERAGE

SeaState now reaches every coast on Earth. Whether you're sailing the Mediterranean, surfing in Indonesia, fishing the Great Barrier Reef, or crossing the North Atlantic, the same trusted data engine powers every pin you drop. No region locks. No gaps.

THE 24-HOUR WAVE HEIGHT GRAPH

The new wave height graph shows exactly how swell builds and fades through your day — from flat to 8 feet and beyond. One glance tells you whether your window opens or closes before you ever leave the dock.

WIND, REDESIGNED

The redesigned wind page shows cardinal direction, gusts, and a true compass rose with intuitive directional icons. You'll know instantly which way the wind is blowing and how hard — no decoding required.

AI CAPTAIN'S BRIEF

Stop interpreting forecast tables. The AI Captain's Brief delivers plain-English go/no-go advice tuned to your specific vessel, powered by Apple Intelligence. Tell SeaState what you're skippering, and it reasons through the conditions like a seasoned first mate standing watch beside you.

PASSAGE PLANNING

Plan dock-to-dock with waypoint-by-waypoint forecasts, Dock-to-Dock ETA, and real-time updates delivered through Live Activities and Dynamic Island. SeaState keeps your passage plan alive while you're underway.

SAFETY HUB

Emergencies don't follow a schedule. SeaState's Safety Hub includes geo-aware emergency contacts for your location worldwide — USCG, UK Coastguard, AMSA, EU 112, and beyond — plus float plans and a full trip log, all in plain English. Your crew and family always know where you are.
