Episode 2 – Illustrations
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 !
This unfortunate sailor - for which I would like to thank him - forced me to make a determined search for the cause of the problem.. 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.

To follow up on complete renewal of weather and ocean forecasting models in the latest version of the three Weather4D applications (Lite, Routing, Routing & Navigation) the revised English and French User Guides are now available to download. Read more …
Latest releases Lite, Routing, Routing & Navigation arrive with a full renewed list of weather and ocean models in order to allow users to benefit from the evolution of the offer of international forecasting models. At the same time, all GRIB files go to format GRIB-2, this allows for a reduction in their size and a better compression ratio. Read more …
Following the prediction of an episode El Niño started in March 2023 (¹) and confirmed the following June (²), this climatic phenomenon of the Pacific Ocean, called ENSO (El Niño Southern Oscillation), strengthened until the end of December, early January 2024.
The February ENSO forecast developed by the U.S. Climate Prediction Center predicts that we are on the eve of an episode La Niña, even though the Pacific Ocean is still affected by the El Niño episode. According to the forecast, there is 79 % chance that El Niño will become neutral by April-June, and 55 % chance that the Pacific will return to ENSO La Niña between June and August.
Since the arrival of ARM-based Mac (M1… M3…) and the system macOS 11 Big Sur, Weather4D Routage & Navigation works natively on our favorite computers (¹). But this happy event did not go, since then, without some small restrictions. The most annoying for users was, until this day, loss of distance calculation. This is carried out on touch devices by a two-finger long press, no function allowed the translation of this gesture on Mac. The mouse only has one pointer, not two ! Read more …
20 years after NMEA 2000 and more than 40 years after NMEA0183, OneNet® is the third generation NMEA standard for marine data interfacing and networking.
In development since 2010 by NMEA members (1), to be published in late 2021, the OneNet standard is based on the IP Internet Protocol (2) version 6 (IPv6) and works on the IEEE Ethernet local network 802.3. This new standard aims to combine the three NMEA data standards — OneNet, NMEA 2000, NMEA0183 — on a single local network (LAN). Read more …
Since taking over MacENC at the end of the year 2020, become MacENCx64 (¹), it took three painstaking years for the company NavStation LLC to finalize the implementation of a global charting. Since January 1 2024 it is now done. A long negotiation with the ENC charting distributor ChartWorld (²) has enabled the creation of a range of vector charts in ENC S-57/S-63 format (³) as in-app purchase. Read more …
