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.

very difficult to learn


I have spent many hours trying to figure out how this site works. My $400 may have gone up in smoke becasue of the poor instructions. The on line tutorial is by a person speaking too quickly with his light hearted music in the back ground. SLOW DOWN and turn off the G-D music. . Take it one step at a time. We are not all 13 years old. tutorial means you are teaching someone something, not just advertising your product. This is a complicated product to use so try to help us.

Developer Response

Please contact us at to help you get started. None of our online tutorials have background music, so think you must not be looking at an official PredictWind tutorial.

Just plain excellent! Just finished 30th roundtrip to Fiji on our Swan 48 Trumpeter. Writing this from Opua, New Zealand.
All downloads for Euro and GFS and both predictwind analysis took between 6 and 8 minutes with the Iridium GO. The forecasts were very accurate and the routing was key in my decisions when to lay Opua. Getting 4 forecasts every 12 hours at sea is pretty darn cool…I love this technology! Get It!!!



Very easy to set up and use. Great, fun, cool
