SURF • A rating for every hour matched to your level, wave size on the body scale and the best slot of the day. • The spot view: every incoming swell in its own colour, with the wind. • Data from an offshore wave model — honest, never oversold as a spot-grade reading. SPOTS EVERYWHERE • Over 1,100 kite, wing, windsurf and surf spots in France, on the map and in search. • The great kite spots of the world — Tarifa, Dakhla, Egypt, Brazil, South Africa… — with new countries added in every update. • Surf spots worldwide.

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.
