For the day and the day after

The best model is Arome HD. It is available for French coasts as well as for Great-Britain up to 53° North. The 1km resolution of this model offers the best and it will soon be updated 8 times a day. It gives wind and temperature forecasts every hour for the following 36 hours. The high-quality and the sharpness of this model generated by Meteo France enables to anticipate the wind direction shifts all day long, as well as the strengthening or the calm period. The relief is also taken into account in this model which brings out the cape accelerations and the wind shadows.

As a yachtsman, you can chose the best time of the day to sail. At night, you will be able to settle on a sheltered anchorage, being almost certain that a night breeze won't bother you by rolling your boat.

As a competitor, this model gives you a sharper vision of the future evolutions and their wind shifts. We recommand you use the meteogram function to see at a glance the wind evolution for the day.

If you need more information, you can also download the usual Arome model. It has a 2,5 km resolution. It is a little less precise than its big brother Arome HD. On the other hand, it gives the forecasts for gusts, rain and cloud cover, which is extremely useful in case of bad weather. For example, with a North-West regime on our coasts, you can have a 20 knots predicted wind with more than 35 knots gusts.

Arome and Arome HD models are available in the HiRes Europe subscription.

 

For the 3 following days

The Arpège model is today the best model for the European area. You get an hourly forecast for the three following days. Despite the fact that the resolution of the Arpege model generated by Meteo France is only 9km, it is very precise on wind changes all day long, in strength or direction.The Arpege model is available in the HiRes Europe subscription.

 

For 2 to 10 days

The best model beyond two days is the ECMWF-GC model. It stems from the model provided by the European Centre for Medium-Range Weather Forecasts. It is the best model currently available in the world, for medium to long-range forecasts. This model is available in the Racing Europe subscription. Otherwise, you can use the GFS model available in the HiRes subscription. It is clearly less precise but you can also get a 10-days forecast.

 

The current

The model My Ocean IBI is an excellent current model for our coasts. It takes into account the tide currents. Many competitors, such as the skippers of the Solitaire du Figaro use it. The My Ocean IBI model is available in the HiRes Europe subscription.

 

In short

For an inshore sailing and 2 to 3 days needs, take out the HiRes Europe subscription and use the Arome HD, Arome and Arpege wind models and the My Ocean IBI current model.

If you need a high-quality forecast beyond 2 to 3 days or if you consider a few days crossing, the Racing Europe subscription will suit you best. It will provide you access to the ECMWF-GC model.

Note that in all paid subscription, you get the Squid routing function which enables you to chose the best way whatever the length of your navigation.
