Navimeteo Forecasting Service for the Atlantic is available for both sailing and powered boats. For such long range navigation, it is strongly recommended for captains/skippers to have a computer onboard and to make use of a weather routing software like NavimeteoSat.

All routes are constantly monitored 24 hours a day and together with details wind, sea, precipitation, Navimeteo Forecasters will also provide useful routing suggestions inferred from weather model simulations, keeping always safety in mind.
Fuel requirements are also taken into account.
Unless weather routing is needed for a regatta where you have to deal with any weather, plans should be kept open on the departure date as much as possible when sailing for pleasure, especially if leaving from high latitudes where weather conditions can vary quite a lot. The Hurricane season in the Caribbeans must also end before crossing the Atlantic.
You should also not fix your arrival date in the diary as corrections from a direct passage (the orthodromic route) may not be reliable when high seas and squall lines force you to change course to avoid adverse weather along the route.
In most cases, sailing passages of the Atlantic from East to West are usually easier and quicker than the opposite way because sailors can pick up the favourable trade wind flow in the area between the Azores and the Canary islands.
In an eastward passage, passing the Bermuda islands, sailors are more likely to be in the tracks of the North Atlantic depression. Leaving from northern Europe, the toughest part of an Atlantic crossing is usually getting across Biscay.
