The Avalon Offshore app includes automatic access to NOAA weather models: GFS 0.25 degrees and GFS 1 degree.

It also allows you to manually load weather files (in grib1 or grib2 format) directly into Avalon.

The Premium Subscription option includes the automatic loading of approximately 85 weather models (winds, gusts, waves and currents), including those specially compressed for satellite transmissions (Iridium Go, Inmarsat, etc.)

You can subscribe directly from the application. This subscription is automatically renewable. You can unsubscribe at any time from your Apple or Google account.

Automatic renewal guarantees that the price is fixed at that of the initial subscription.
