Last updated: 04/09/20 With today’s good forecasts and communications this should be easy enough, however reality shows that the day-to-day weather can be quite different from the climatological averages. But sailing and weather is not that simple; the wind shadows and acceleration zones can extend a long way from the Canary Islands. The last time I sailed the ARC was in 2015. The warm surface water moves eastward and reduces upwelling of cold water off the coast of South America. Tradewinds explained: Everything you need to know before sailing across the Atlantic . See more. This line of weather is known as the Inter Tropical Convergence Zone (ITCZ). often trade winds Any of a consistent system of prevailing winds occupying most of the tropics, constituting the major component of the general circulation of the atmosphere, and blowing northeasterly in the Northern Hemisphere and southeasterly in the Southern Hemisphere. Early commerce to the Americas relied on the trade winds—the prevailing easterly winds that circle the Earth near the equator.

The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region (between 30°N and 30°S latitudes). My rule of thumb is to get at least 100 miles south of Tenerife but we have to get clear of the Gran Canaria wind shadow first. Known to sailors around the world, the trade winds and associated ocean currents helped early sailing ships from European and African ports make their journeys to the Americas. Endless sunny days of running before the wind followed by nights under a sky full of stars with dolphins playing alongside…. This area of calmness and almost windless is called the doldrums. Trade winds have been used by captains of sailing shipsto cross the world's oceans for centuries and enabled colonial expansion into th… The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree "belt.". Because of its proximity to the equator temperatures are mild and the length of the day is pretty constant throughout the year. The trade winds blow from subtropical areas of high pressure toward the equator. Trade winds are generally very predictable. Some sailors will choose a route well ahead of time and stick to it. How to cite this article, National Oceanic and Atmospheric Administration. In 2016 (right) the pattern was completely different. Meteorologist Chris Tibbs explains the Atlantic tradewinds and how to use them to ensure a smooth transatlantic crossing, The tradewinds mean that even 22ft wooden sloops like Flying Cloud can cross the Atlantic. Going west first helps avoid a dead run all the way. The gains made by heading west first are that it is in phase with the expected wind swing. The sinking air triggers the calm trade winds and little precipitation, completing the cycle. Trade winds - Trade winds occur near the equator and flow from either the north or south towards the equator. On a long passage, extended forecasts are useful, but look for consistency in weather routing solutions. The Inter Tropical Convergence Zone (ITCZ)is generally located near the Equator year-roun… These winds are favored by sailors because of their warmth and steady stream. Even now, commercial ships use "the trades" and the currents the winds produce to hasten their oceanic voyages.Â. The trade winds blow predominantly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase. There are large initial gains to be made if we can head on a direct route at the beginning of the passage, but at some stage we will have to make a dive south to stay in the tradewinds. Visit TradeWinds for the best news, insight and opinion covering the global shipping business. However, large gains can be made by using the available forecasts and being more flexible. They have been instrumental in the history of exploration, communication, and trade. The rotation of the Earth deflects the atmosphere, resulting in curved wind paths. Even today, shipping depends on trade winds and the ocean currents they drive. The majority of yachts follow the traditional route heading towards the Cape Verde Islands before tracking west. As the wind blows to about five degrees north and south of the equator, both air and ocean currents come to a halt in a band of hot, dry air. Fairtrade, fair trade, direct trade, ethically sourced, organic, rainforest alliance, UTZ, carbon neutral, corporate social responsibility, sustainable…. In 2016 the wind gods were not so kind and it was a year of either going way south or following a northerly course. During normal conditions, trade winds, which blow from east to west, push warm surface waters towards Asia, piling it up in the western Pacific. The Charles W. Morgan is the last of an American whaling fleet that once numbered more than 2,700 vessels. Between about 30 degrees north and 30 degrees south of the equator, in a region called the horse latitudes, the Earth's rotation causes air to slant toward the equator in a southwesterly direction in the northern hemisphere and in a northwesterly direction in the southern hemisphere. The middle route was particularly slow. Over the last few years the record for the ARC has been broken a number of times and interestingly the fastest routes have been both to the north and the more traditional southern route, which just goes to prove that the weather is not quite as settled as averages show. Trade wind, persistent wind that blows westward and toward the Equator from the subtropical high-pressure belts toward the intertropical convergence zone (ITCZ). But sailing and weather is not that simple; the wind shadows and acceleration zones can extend a long way from the Canary Islands. The trade winds are located from 30 degrees latitude, north and south, to the equator.
