Powered by PredictWind's world leading marine weather forecasts, the free offshore app allows seamless downloading of multiple GRIB files for your coastal or offshore passage. The intuitive interface allows you to download and immediately view GRIB files, weather routes, GMDSS Text forecasts and Satellite Imagery. PredictWind's proprietary PWG and PWE marine weather forecast models are available along with the ECWMF and GFS models to provide the most accurate forecasts, available at the highest resolution.

Download and view animated weather forecasts, Weather Routing and Departure Planning for your next offshore passage. The Weather Routing & Departure Planning is calculated on the PredictWind server with the highest resolution forecast data, but the file size is incredibly small, making it ideal for transmission over low bandwidth Satellite & SSB connections.

Works with Wi-Fi, mobile networks, and most satellite connectons using the Iridium GO!, Globalstar, and Optimizer interface in the Offshore App.

What's New

Version 3.2.1

As of version 3.2, you can now download GRIB files without clearing previously downloaded GRIBs, while GRIB age notifications and scrolling performance have improved. Version 3.2.1 makes the weather info map popup more robust.

Ratings and Reviews

Unable to get working


After trying for several hours to get this app to work I have deleted from my iPhone. Tried to enter route south of Australia and could not download files or get a single map to show.

Help files useless to help me

All maps centered on USA suspect works well there but not in Australia

Gave up after several hours of hitting head against US-centric app

Great App with strong developer support


I have been very impressed with this easy to use app that consistently delivers reliable weather predictions in easy to understand format. The developers of the app clearly take a lot of pride in what they do, and their responses to queries have been quick and clear. Without exception the developers have gone that extra mile to make this the very useful app that now forms a corner stone to my cruising.
