Description

Weather4D Lite is a powerful meteorological application based on atmospheric and oceanic data in GRIB format. It benefits from a new interface derived from the “Routing and Navigation” version.
Over 35 weather and oceanographic forecast models are available. Queries and downloads are fully customizable.
The application makes it possible to create your own geographical zones and to select the characteristics of the GRIB files to download: choice of data, resolution, periodicity, file size, etc.
GRIB files are downloaded from APP4NAV’s own servers, but can also be obtained by satellite phone.
Weather4D Lite displays the combined data as layered layers, and fine-tunes the mode and display quality of each data type. All the data of a selected model is displayed by an animation in continuous time scrolling or in manual scrolling on the chart.
The weather forecast is displayed in one or two windows (iPad only), offering several display combinations of the same area: weather forecast and wave or current forecast, comparison of different models. The two windows can be disassociated for displaying the same area at different scales.
Weather4D Lite comes standard with the GFS global forecast model at 0.25 °, 0.5 °, 1 ° and 2 ° resolutions. Two global satellite (BING) and global terrestrial (Open Street Map) cartographies.
Options
High resolution weather models NAM, COAMPS, WRF (USA), GEM (Canada), ARPEGE Global, ARPEGE Europe, AROME, AROME HD (France), AROME (DOM-TOM), as well as wave models WW3 and MERCATOR OCEAN and currents models MFWAM, NCOM are provided in a single pack available by annual subscription (in-app purchase).

Ratings and Reviews

Download and view GRIB data

An excellent app. Invaluable for recent passages across Biscay, Brest-Baiona, and onward via Lisbon, Gibraltar and Calpe, to Ibiza.
It may take some time to learn the nuances of the user interface, but it then allows you to setup areas of interest, download GRIB data, and visualise projections for wind, weather, waves and currents in various combinations.
Many thanks to L'Échappée Belle (a well-travelled Harlé Jurançon) for pointing us to this app in Morgat (Brest) on 5 Jul 2014.

This is certainly the best GRIB file viewer that I have used (and I have tried most of them!) It is very feature-rich and well worth spending time getting to know. In addition to displaying the standard (free) GRIB Files there is an option to purchase a higher resolution WRF model. Well worth the extra if you intend to use it for any serious sailing. Support questions are answered promptly and clearly.
