Bean > the odd thing is that's not really a sea change, but a change of wind direction. wow's example is also called a sea breeze or onshore wind.

Oh, yes, Bean! Here in NE, though, we distinguish ... the sea change being the actual turn of the breeze relieving the 3H conditions and a sea breeze is a type of weather, continuous mostly, as is an on shore wind.
Surfers are not fond of the onshore breeze .. they turn the waves to mushy froth.
