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 emphasised 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.

Pilot Atlas NGA Digital Navigation Publications.

Pilot Atlas's for the whole 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.
