Understanding weather forecasts is one step, but knowing about weather detail is another.

Much of our weather, and particulrly weather that really affects sailors is often rather small scale. It may be predicted in general terms but rarely in detail. These pages have been written to help sailors understand about some very local effects that are not always well explained in text books or the sailing ,magazines. On some pages, conventional wisdom is challenged.
