Theyr, the London based advanced weather-forecast provider, specialising in the maritime and wind energy sectors, has announced the launch of its digital precision weather and ocean forecasting app for maritime professionals. GRIBview mobile delivers high-definition weather and ocean forecasting technology for mobile devices.

“Theyr provides data to many of the world’s best know maritime organisations, companies and brands,” said David Young, managing director of Theyr. “By supplying forecast information on such a refined scale, we provide the mariner with the best possible understanding of future weather and ocean events; in turn, this greatly informs their decisions, whether tactical planning for racing or defining the safest route for bluewater sailing.

“B&G, Fugawi Marine 5, iNavX, Lowrance, NavigationPLANNER, PCPlotter, Raymarine, Simrad, TRANSAS iSailor, and Yachting & Boat World, as well as the British Marine Federation, Royal Ocean Racing Club and Royal Yachting Association are just some of the companies that rely on the Theyr forecasts”, Young added.


GRIBview mobile provides free and unlimited GRIB downloads for the Global Forecasting System (GFS) – GRIdded Binary or General Regularly-distributed Information in Binary form (GRIB) being the format used by the world’s meteorological institutions to manipulate weather data into observable visual data. These downloads will include GFS data at one-degree resolution, and high-resolution data down to one kilometre resolution.

Additionally, subscriptions to high-resolution premium weather data packages are available; they include wind speed, barometric pressure, precipitation, air temperature, sea surface temperature, significant wave height, period and direction.

The new app provides a variety of packages to suit the varying needs of marine professionals. All packages come with the same user-friendly interface and an ability to save and store historical data for use when offshore and offline. The inclusion of a mobile app in the Theyr portfolio completes its multi-platform system, with users able to use the same format online, on tablet or on a mobile phone.
