There’s a persistent myth among sailors: “Use GRIB files, they’re more professional than your Windy.app.” But let’s break this down, as it’s not as straightforward as it sounds.
What Are GRIB Files?
First off, GRIB stands for GRIdded Binary, and it’s just a file format used to compress and transmit weather data. GRIB files store forecast data like wind, temperature, and pressure and are used by many weather models, including the GFS, ECMWF, and regional models like WRF.
But here’s the key point: GRIB is not a weather model—it’s just the way the data is packaged. You can access GRIB files through various apps and software, but the data inside them comes from the same forecast models that many weather apps use, including Windy.app.
What About Windy.app?
Now, let’s talk about Windy.app. This app allows you to choose between different weather models, such as ECMWF, GFS, ICON, and others, displaying data in a user-friendly interface. Essentially, Windy.app is a visualisation tool that reads the same GRIB files used by more technical programs. The difference? It presents the data in an intuitive way, making it easier for sailors to interpret weather conditions.
So, Is One Really More Professional?
The myth that GRIB files are more “professional” comes from the idea that they’re used in more complex, technical programs like OpenCPN or Expedition. While these programs offer more advanced features, they’re not necessarily better for day-to-day sailing decisions unless you need those specific tools. For most sailors, apps like Windy.app give you the same data (from GRIB files), just in a more digestible format.
The Bottom Line
GRIB files and Windy.app aren’t competitors—they’re part of the same ecosystem. Windy.app reads GRIB files from models like GFS or ECMWF, so you’re not missing out on any “professional” data by using the app.
In fact, for the majority of sailors, Windy.app offers all the precision you need, without the hassle of manually downloading and reading GRIB files. Unless you’re a navigator on a racing yacht with specific data needs, Windy.app will likely do the job just fine.
Conclusion
The idea that GRIB files are more “professional” than Windy.app is pure nonsense. Both GRIB files and Windy.app rely on the same weather models. The real question isn’t which one is more professional, but which tool works best for your needs.
For most sailors, Windy.app offers the convenience and accuracy needed for planning safe voyages, without having to dive into technical software. So, sail smart and choose the tool that works best for you!
