Winds:

Make a study of the winds in the locality in which you sail. You will find that nine times out of ten they go through the same routine in shifting. By learning the manner in which they change you can take advantage of these shifts. The winds in summer generally follow the sun in its circuit, until they get back to their proper place. If they go the other way, what is called back, you can never trust them to stay long, and it is usually a sign of bad weather. In sounds and estuaries the wind usually comes in with the flood tide. If this tide makes in the morning the wind will stay all day; if the flood makes in the p. m. hours it will not last long. If the wind comes in strong against the tide look out for a long blow. Offshore winds usually come and go with the sun, reaching their maximum velocity at noon and midnight.
