ECMWF IFS 0,1° (9 km) 0.25° (28 km), 0.4° (44 km), 1° (111 km) Global model from the European Centre (ECMWF). Often considered the most reliable for medium-range forecasts. Resolution: from 29 km up to 111 km Forecasts up to 10 days 👉 A key reference for offshore navigation. Prefer the high-resolution version (0,1°) for a small area, (0.25°) with a good connection for a larger area, or a lighter version (0.4° or 1°) when bandwidth is limited and the area very large.
ECMWF AIFS 0.25° (28 km), 1° (111 km) Brand-new model from the European Centre (ECMWF) using artificial intelligence.
Resolution: 28 km or 111 km
Forecasts up to 10 days
👉 Interesting for testing AI model performance and having an alternative to traditional models. Improving day by day — already likely better than ECMWF IFS and GFS for forecasts beyond 7 days.
GDPS (GEM) 0.15° (17 km) Global model produced by Environment Canada. One of the finest-resolution global models available. Resolution: 17 km Forecasts up to 10 days 👉 Relevant for North Atlantic crossings and high-latitude sailing near the Arctic.
ICON Global 0.25° (28 km) Global model from DWD (German Meteorological Service). Resolution: 28 km Forecasts up to 7 days 👉 A solid alternative to GFS and ECMWF IFS, particularly for sailing in Europe and the Mediterranean.
Arpege Global 0.25° (28 km) Global model from Météo-France. Resolution: 28 km Forecasts up to 10 days 👉 Useful for offshore sailing near France, in the Atlantic or Mediterranean, as it is well tuned for these areas.
