Pilot Charts for Passage Planning

A pilot chart, or atlas, amongst other things, provides a month-by-month, grid-by-grid graphical representation of wind speed and direction based on historical data. The idea being to enable passage planning using the probability of favourable wind speed and direction for different possible routes at different times of the year. It must be emphasized that these charts are compiled on historical data and the winds actually experienced on a particular route may be quite different to that shown on the charts. Having said that, they are most useful in planning a route to give one the best chance of getting favourable conditions, for example, taking advantage of seasonal winds such as the Trades, and many other very predicable winds throughout the world.

These are downloadable, full colour pilot charts. They are fairly big so you will need either a fast link or plenty of time. You can view them online but if you wish to refer to them often it would be much faster to load them onto your own computer and then view them offline at your leisure.

I gotta ask,

You seem to have a tremendous wealth of information which is great to have access to. What is it that you do? Your posts are always right on and very detailed. I would guess that your desk is also very clean.

Thanks for the kind words.
You'd be absolutely wronge about my desk, which is often & currently a total disaster. Of course, I've been away a fortnight, so I've some excuse at this time.
I'm working as a project coordinator / inspector for a Mechanical-Electrical Engineering firm.
I spent the 1990's living aboard - cruising the Bahamas (winter) and operating "Southbound Marine" summers. Southbound Marine specialised in premium yacht re-fit projects.
