Description
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.
ONE ANSWER, FIRST
Open the app and you get a verdict, not homework. Today's GO, CAUTION or NO-GO with a score tuned to your boat, then a swipeable week showing peak wind and wave height for every day. The official NWS marine zone forecast sits right underneath, in plain English, free for everyone.
WIND, HOUR BY HOUR, A WEEK OUT
Scan the next 24 hours at a glance, or open any day for a full hourly breakdown with direction, gusts and peak wind. Cardinal direction, a true compass rose, and the Beaufort scale — no decoding required.
WAVES IN PLAIN NUMBERS
Wave forecasts read like a person wrote them: the height, plus whether that means flat, light chop, a bumpy ride, or stay in. Calmest and roughest hours called out up front.
ANCHOR WATCH
Set your swing circle after the hook is set, then sleep. If the boat drags outside the circle, SeaState sounds the alarm — on your phone, your lock screen, the Dynamic Island, and your Apple Watch. Two-fix confirmation means no 2 AM false alarms.
FIND THE FISH
Sea surface temperature and chlorophyll layers from NASA satellites reveal the temp breaks and colour changes that hold fish. A built-in guide teaches you how to read them, and a lockable temperature window makes breaks jump off the screen.
OFFICIAL NOAA CHARTS
Real ENC nautical charts with depth soundings, buoys and hazards, at three detail levels. Tiles cache to your device so the chart still draws when the signal doesn't.
PIN ANYWHERE. COMPARE ANYTHING.
Drop a pin on any water on Earth for live waves, swell, wind, tides and water temperature. Compare two spots side by side — the windward and leeward sides of an island at once, or two anchorages before you commit.
CONNECT YOUR BOAT
Feed SeaState from your NMEA Wi-Fi gateway for live depth, wind and speed off your own instruments, plus AIS traffic drawn directly on the chart.
A BAROMETER THAT LOOKS AHEAD
Most barometers tell you what already happened. SeaState forecasts pressure 48 hours out and calls out the sharp drops that mean a front is coming, before it arrives.
AI CAPTAIN'S BRIEF
Stop interpreting forecast tables. The Captain's Brief delivers plain-English go/no-go advice tuned to your specific vessel, and explains the interactions that matter — wind against current, short steep chop, unstable gusts.
SAFETY HUB
Emergencies don't follow a schedule. Geo-aware emergency contacts for your location worldwide — USCG, UK Coastguard, AMSA, EU 112 and beyond — plus Man Overboard tracking, VHF scripts, and float plans so your crew and family always know where you are.
