WeatherTrack GRIB Discussion

Open discussion

Range of iPhone/Weathertrack

Weathertrack does work all the way on your voyage, especially as it downloads the GRIB files and does not need any Internet access for displaying the downloaded data. However, you do not have cell phone coverage for parts of your voyage that are offshore, e.g. more than about 6 miles off the coast.

For example for doing offshore sailing, you can download weather forecasts before starting the voyage to peruse while sailing. We do it while still having WIFI access, for example in a beach bar or in a marina, so save on roaming costs.

But if you want to get the latest forecasts on long offshore passages, say for crossing an ocean, you need another technical solution to get network access to GRIB files:

1) Either via satellite phone (which incurs costs per minute)

2) via SSB radio

If you have more questions, feel free to ask here.

There was a discussion on how to share files with iTunes and WEATHERTRACK here:


So the easiest would be to connect the iPhone/iPad with the USB cable to your computer and transfer files there. We for example use that to put GRIB files received by SSB email for offline viewing onto the iPad.

The map in WEATHERTRACK is specifically designed to work offline, users do not need an Internet connection to use the map.
