@maritimemaster: Flat calm at ten in the morning, force four by two in the afternoon, and calm again by dusk. That is the sea breeze, and it is one slow loop of air: the land heats far faster than the sea, the warm air over it rises, and cooler sea air slides in underneath to fill the gap. It adds to whatever the forecast already gave you, it fades in the evening, and overnight the whole loop can run the other way as a lighter land breeze. #seabreeze #sailing #weather #learntosail #coastalsailing
