Route: Yachts leaving the Galapagos Islands for the Marquesas are recommended to sail south or south-west as the wind direction allows, along 90W, until the South East Trades become stable, which is generally around 3 -4 South (See Note below). Then head west towards a waypoint around 6S/100W and from there directly towards the Marquesas.
Note: It should be noted that south of Isla Isabela is an area with often calm or light variable winds, this being the reason it is recommended to leave the Galapagos setting a course south as indicated above.
Wind Direction: South East Trade Winds first from the SSE and as moving westwards becoming more easterly, even at times before reaching Marquesas ENE winds can be experienced. Wind force average 10-20 kt. with variations within a 24 hour period. Stronger or lighter conditions can also be experienced in periods. Infrequent light to moderate convection with gusts and/or squalls. In periods also Trough Systems present eastern part of the area, east to west direction.
Sea: Swell from Southwest/South/Southeast 6-9 ft. average, at times higher, actual direction depending on weather systems (High & Low-Pressure systems) passing west to east south of the area. Swell generally large and long. The disturbed sea can also be experienced in periods.
Current: South Equatorial Current west/northwest moving.
Weather: In general terms, the daily weather information/forecasts will provide actual predicted conditions.
