I. Sailing across the Atlantic: understanding the possible routes

What is a transatlantic sailing crossing?

A transatlantic sailing crossing is a passage linking Europe (France, Spain, Portugal) or Africa (Cape Verde) to the shores of the Americas. It is offshore sailing, several thousand miles long, and it can last several weeks depending on the route and the weather.

From the first explorers to today's sailors, all of them share the ocean and the challenges it offers.

Outbound crossing: Europe to the Caribbean

The outbound crossing takes place between October and December, via the Canaries and often with a stopover in Cape Verde. It makes the most of the north-east trade winds in the Tropics.

• La Rochelle → Canaries: 18–20 days (~1,400 miles).
• Canaries/Cape Verde → Caribbean: 20–25 days (~3,000 miles).
• Total ≈ 5,500 nautical miles.

Return crossing: Caribbean to Europe

In spring, boats head north via the Azores. The trade winds are less steady and low-pressure systems more frequent.

• Distance: ~4,500 nautical miles.
• Duration: 45–50 days.

II. Best time for a transatlantic sailing crossing

Choosing the right moment is essential to avoid hurricanes, winter storms and headwinds.

• Avoid the Caribbean hurricane season (June ‑ November).
• Don't set off in the depths of winter across the Bay of Biscay.
• Ride the trade winds for a steady, fast crossing.

Best time for an outbound crossing (Europe > Caribbean)

Ideally between November and December: established trade winds, mild climate, low hurricane risk.

Best time for a return crossing (Caribbean > Europe)

Between March and May: end of the tourist season, more settled weather in the North Atlantic.

Other factors:

• Seasonal weather conditions.
• Prevailing winds (trade winds).
• Regatta calendar.
• Availability of a transatlantic crew member from the Canaries.

III. Transatlantic departure ports: where to leave from depending on the route

Departure ports for the outbound crossing

• La Rochelle and French Atlantic ports.
• Cascais, Lagos, Lisbon (Portugal).
• The Canaries (Las Palmas).
• Cape Verde (Mindelo).

Las Palmas (Canaries): a strategic choice

• Steady trade winds.
• Last well-equipped stopover.
• Modern facilities.

Recommended ports for the return crossing

• Pointe-à-Pitre (Guadeloupe).
• Le Marin (Martinique).
• Rodney Bay (Saint Lucia).

IV. When to set off to cross the Atlantic by sailboat?

Summary of recommended periods

• **Outbound crossing **: November-December (France → Canaries → Caribbean).
• **Return crossing **: March-May (Caribbean → Azores → Europe).

How to choose the right moment to leave

• Watch the marine forecast for several weeks beforehand.
• Check the boat's maintenance and safety.
• Put together a crew you can trust or sign up as a crew member.
