Squalls, time of:
Squalls on the seacoast generally come off at either high or low water. If they come between tides they are apt to be bad ones. If your feelings or the barometer tell you a squall is likely to come off, carefully watch inshore for the appearance of the wind. White squalls—that is, sudden blows unaccompanied by cloud or rain, are the most likely to catch you napping. They sometimes precede a sudden change of wind. If you see the water suddenly whiten inshore, look out for trouble, and lower all sail at once.
