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.

A have to have companion at see

I use predictwind/offshore application by more than one year. Actually, I have passed 7 seas and I am on the way to cross the Atlantic Ocean. In more than 95%the forecasts have been accurate and the mathematical model used let you a plenty of options to choose a departure schedule or to make a passage.

Doesn't work on the iPod

Great app in combination with an IridiumGo on iPhone and iPad. For some reason doesn’t work on my iPod Touch. I have reported this to Iridium but it's been months now. Should be an easy bug to fix, no reason for it not to work on the iPod Touch.

Works great with Iridium Go

Used both the IOS and Mac version on a recent passage.

Both were intuitive and seamlessly linked to Iridium Go. While it is a little easier to add coordinates in the Mac version, I found the convenience of the IPad outweighed this minor inconvenience.
