What is meant by a sea turn as it relates to wind?

In New England, a sea turn is an easterly sea breeze that comes on cool, from the offshore waters. As a weather prognosticator, it can frequently indicate low clouds and fog or, in some cases, a mild rain. Spring and early summer are the times for sea turns, although they can occur at other times, as well. A sea turn is just one version of a sea breeze (as distinguished from a land breeze, with its milder effects).
