BAHAMAS → BERMUDA → AZORES
Bahamas – Bermuda – Azores
Crossing from The Bahamas to Bermuda to the Azores in May is a classic transatlantic route favored by many bluewater cruisers heading to Europe. Here’s a breakdown of the route, conditions, and considerations for each leg:
🟦 1. Bahamas to Bermuda
Distance: ~780 NM from Eleuthera/Abaco to St. George’s
Typical Duration: 5–7 days
Best Time: Late April to mid-May
⛵ Conditions:
-
Prevailing Winds: East to southeast trades, 10–20 knots.
-
Weather systems: Watch for cold fronts exiting the U.S. East Coast. These can bring squalls and NW winds.
-
Currents: You’ll skirt the Gulf Stream, but don’t aim directly through its strongest parts; stay on its eastern edge.
-
Routing : Wait for a weather window with SE-SW winds ahead of a front, then ride the shift N-NE to Bermuda
-
Average wave height: 1–2.5 meters (3–8 ft)
-
Sea pattern: Generally moderate trade swell mixed with wind-driven chop.
-
Gulf Stream Influence: If you get close to the stream, expect steep, confused seas especially if wind opposes current (e.g., NE wind against northbound current = square waves and breaking crests).
-
Best Strategy: Route east of the Stream and time departure before or after a frontal passage for cleaner following or beam seas
🔄 1. Bahamas to Bermuda – Currents
✅ Main Concern: The Gulf Stream
-
Flow: ~2–4 knots northward
-
Location: From Florida Straits eastward to ~73°W
-
Effect: If you cross it perpendicularly, you’ll get through quickly. If you sail along it, it can speed you up—or severely slow and toss you if wind opposes it.
-
Best Practice:
-
Route east of the main core of the Stream when possible.
-
Watch for eddies—they spin off and may carry NE or SW flow.
-
Get real-time data via NOAA Gulf Stream Analysis or PassageWeather.
-
🌀 Eddies (spin-offs from the Gulf Stream)
-
May assist or hinder depending on position.
-
Can be up to 1 knot and last days/weeks.

🟦 2. Bermuda to Azores
Distance: ~1,900 NM
Typical Duration: 12–18 days
Best Time: Mid-May to early June
⛵ Conditions:
-
Winds: Variable — expect anything from SE trades to light airs, with possible gales from mid-latitude depressions.
-
High Pressure: The Azores High often expands NE this time of year, creating large calm zones. Engines may be needed.
-
Lows: North Atlantic depressions track above 35°N, but can dip south. Routing slightly south (~32°–35°N) may avoid worst of these.
-
Routing : Some cruisers head ENE at first, then curve east or southeast depending on GRIBs.
-
Average wave height: 1.5–3.5 meters (5–12 ft), but can spike to 4–5 m (12–16 ft) in passing lows.
-
Wave period: Often 8–12 seconds, but can shorten drastically in rougher conditions.
-
Cross seas: Common — leftover swell from previous systems (NW to W) combined with current wind-driven sea (E to SE) can result in confused, lumpy motion.
-
Calm Zones: If trapped in the middle of the Azores High, expect long rolling swells and glassy calm with some leftover chop.
-
Worst case: A passing low can bring sustained 25–35 knots and seas building to 4+ meters if you’re too far north.
🔄 2. Bermuda to Azores – Currents
🌊 North Atlantic Subtropical Gyre
-
Dominated by the Azores Current and North Atlantic Drift
-
Average flow: 0.5 knots or less, generally eastward or southeastward
-
More benign than Gulf Stream — but slow currents can help or hinder over long durations
✅ General Strategy
-
Below 35°N: Currents tend to be weak and variable; routing focuses more on avoiding lows than riding currents.
-
Above 35–37°N: You may tap into light westerly-setting flows, but you also risk getting closer to stronger systems and rougher seas.
Preparation & Planning
-
Fuel: Ensure ample diesel for motorsailing (especially Bermuda–Azores).
-
Weather Tools: Use PredictWind, Saildocs, NOAA OPC, and get forecasts via Starlink – Iridium GO, Starlink, or SSB.
-
Safety: This is an offshore ocean passage — have liferaft, EPIRB, AIS, storm sails, and proper watch routines.
Notes from Cruisers
-
May offers one of the better weather windows before hurricane season and before the North Atlantic becomes too unsettled.
-
Boats often gather in St. George’s, Bermuda for final prep and wait for a good window.
-
The Azores (usually Faial/Horta) are a welcoming and essential landfall, with fuel, repairs, and a strong cruiser community.
