Changes have been made to the available ocean GRIB models :
Tuesday 25 February 2025, A new version of the deterministic model of the artificial intelligence forecasting system (AIFS) has been published and operationally implemented. This update marks a turning point in ECMWF's history, since AIFS Single v1 is the first AIFS model to be rendered fully operational (¹). Read more …

Forecasts IFREMER (see Episode 1) available in Weather4D are of two kinds :
These files concern areas of the Channel and Atlantic whose coverage and resolutions are significantly different. Read more …
Episode 1 – Description
Since 7 May 2024 the latest versions of Weather4D have been enriched with several new weather and ocean models (¹). Among the latter, ultra-high resolution current and wave forecast models from’Ifremer come in addition to Copernicus models (formerly called MyOcean) for the Channel and Atlantic coasts. These forecasts are provided with hectometric grids, can be reduced up to 190 meters for some models. So Ifremer, what is ? Read more …
An incomprehensible malfunction occurred recently for a Weather4D user, sailing in a “lost hole” on the edge of the Indian Ocean, namely the Cocos Islands, challenged me to the point of getting lost in conjectures. A GFS file due ten days ago categorically refused to be displayed in the application with the date, damn !

After much procrastination, explorations of settings that may be faulty, since no other user had reported such a problem to us, the light finally came out ! Read more …
As part of the gradual conversion of raster charts to vector charts ENC (¹) on the platform Geogarage, Weather4D Routage & Navigation now includes the following ENC catalogs :
These ENC catalogs are added to the previous ones already available (Spain, Croatia, Germany, Netherland). Others are under negotiation such as Greece and Sweden.
