Where the forecasts come from

Forecasts come from Open-Meteo, which aggregates the models of national weather services. They cover today and the next 10 days.

GoMarine fetches them every hour and recalculates your windows. The “Updated … ago” label on each card tells you how old the latest forecast is.

The app reloads on its own when you reopen it. To force an update, tap Refresh.

These forecasts are estimates. They do not replace official weather bulletins or observation on site.
