Nope, but I found this:

Over the sea, the same effect is quite common in some areas. This is when moist air flows across the sea towards colder waters; the cooling gives Advection Fog that we call Sea Fog. First, it is important to note that sea fog can occur at any time of day and with quite strong winds. With winds over about F 4-5, the result may be low cloud and poor visibility rather than fog. In the English Channel, sea fog can occur at any time of the year but seems to be more common in the late Spring and early to mid-Summer when the water inshore is still fairly cold.
