About the book

While Lady Luck often determines if you’ll be in the right place at the right time, Cornells’ Ocean Atlas can help you avoid being in the wrong place in the wrong season – the goal of every navigator.

Jimmy Cornell, experienced sailor and bestselling author, has teamed up with his son Ivan to produce a fully updated and revised second edition of Cornells’ Ocean Atlas aimed at navigators planning an offshore voyage.

Eighty monthly pilot charts of all oceans for the world show wind speed and direction, current speed and direction, approximate extent of the Intertropical Convergence Zone, the most common tracks of tropical storms, and the mean location of high pressure cells for each hemisphere.

Sixty detailed charts of the most commonly sailed ocean routes make it easier to plan a route that takes best advantage of the prevailing weather conditions at that time of year.

Sidebars with tactical suggestions have been added to the months when most passages are undertaken. The comments and tips on tactics, as well as weather overviews for each ocean, were contributed by meteorologists and routers specialising in those ocean areas.

The new edition has been reformatted to incorporate a new feature: monthly windgrams for the most sailed ocean routes.

Windgrams are a summary of wind strength and direction derived from the individual windroses along a specific ocean route. They will greatly simplify the work of planning specific ocean passages by showing at a glance a visual summary of wind conditions along the entire length of a chosen route.

Windgram of the winds between the Galapagos and Marquesa Islands in March. The colour indicates the wind strength on the Beaufort scale (dark blue force 4, light blue force 5, etc.)		Windgram of the winds between Newport, R.I., and the Azores in June.

The first edition, published in 2012, was based on satellite observations undertaken in the previous 20 years (1991-2011).

The second edition is fully revised and updated by incorporating data gathered during the last five years (2011-2016). The data now spans 25 years and reflects any changes that have occurred during this latest period.

Although the initial edition of the atlas was aimed at owners of sailing yachts, because there is no other publication dealing with offshore weather conditions, the atlas has also been bought by owners of motor-yachts, cruise ship companies, commercial fishing boats, and even military naval ships.

Book reviews

Readers reviews on Amazon:

A great idea to utilise the modern data by NOAA as a basis for these accurate and well layed out pilot charts.

Pilot charts really are invaluable for passage planning and these are the best there are.

Cornells’ newly published pilot charts are the answer to the cruiser’s quest for up-to-date reliable statistical meteorological information.

For anyone used to the wind and currents charts this is a complete atlas of all the world’s oceans. A huge amount of information distilled into 120 pages.
