Seander helps you decide where to anchor and when to go, with a clear read of marine weather tailored to each anchorage — not just a generic forecast for the area. Check marine forecasts, explore Mediterranean anchorages, save your spots, and get a quick interpretation so you can sail with more judgement and confidence. What you can do with Seander: • View wind, swell and the day’s evolution, with a full forecast expandable from Home. • See each anchorage’s status (comfortable, fair or rough) based on wind, sea state and shelter protection. • Explore anchorages and harbours on the map, with detail sheets, comfort timeline and shelter rose. • Ask Seander Advisor in plain language: should I stay here?, where should I anchor?, how’s the weather evolving? • Save favourite locations and see top picks nearby when conditions allow. • Use the app in light or dark mode, built for daytime checks and night watches on board. Seander is built for skippers, crews and sailing enthusiasts who want useful, direct, actionable information — less noise, more judgement before you leave.
