No guessing games, no scrolling through ten weather apps. Swipe the 7-day outlook for peak wind and wave height at a glance, then drill into hourly wind a full week out with gusts, true direction and Beaufort scale. The official NWS marine zone forecast comes straight from the source, written in plain English, free for every user. No subscription wall between you and the forecast that actually matters. See the whole picture on the chart. Toggle official NOAA ENC charts over Apple Maps for depth soundings, buoys and hazards at three detail levels, cached for when you lose signal offshore. Animated wind and current particle layers show you what's actually moving out there. Drag the time scrubber through the next 48 hours and watch conditions shift before you leave the dock. Tide stations are now plotted right on the chart. Tap any station for a 24-hour tide curve with the next high and low, so you can time the cut or the flat right. Have an AIS receiver aboard? Connect your boat's NMEA Wi-Fi gateway to see live depth, wind, water temperature and nearby vessel traffic on the chart, working offshore with no cell signal. Dropping the hook? Anchor Watch guards your position with a drag alarm and two-fix false-alarm protection, backed by Live Activity, Dynamic Island and Apple Watch alerts. Sleep easier. For the fishing crowd, sea surface temperature and current layers help you find the edges and breaks where fish stack up. SeaState is built for offshore anglers, cruisers, sailors, surfers and captains who want a straight answer, not a maybe. Download it and know before you go. SEASTATE PRO Unlock the full experience with SeaState Pro, available as monthly ($4.99) or yearly ($39.99) auto-renewing subscriptions, or a one-time lifetime purchase.

Know before you go. MarineWise combines tides, marine weather, solunar periods, and a daily fishing score into one app built for boaters and anglers. MARINE WEATHER Wind speed and direction, wave height and period, and sea surface conditions from Open-Meteo — 7 days out. Know what the water looks like before you leave the dock. TIDE PREDICTIONS NOAA-sourced tide charts and predictions for thousands of stations along the US coastline. See the full tidal curve, high and low extremes, and tide timing for any day. DAILY FISHING SCORE Every day gets a 0–100 score calculated from the factors that actually affect fish activity — tidal movement, solunar peaks, barometric pressure, wind conditions, and prime feeding windows. No guesswork. One number tells you how good the day looks before you leave the dock. SOLUNAR FORECASTS Major and minor feeding periods calculated from the moon's position for your exact location. See moonrise, moonset, moon phase, and the daily solunar timeline at a glance. TRIP PLANNER Pick a date and get a recommendation with a suggested departure time based on tide windows, solunar peaks, and weather conditions combined. BUILT FOR THE WATER - Save favorite locations for quick access - Offline-friendly — data loads fast and stays cached - Dark interface designed for bright sunlight and early mornings - No account required. No ads. MarineWise is for recreational planning only. Always check official sources before heading offshore.
