Tide Affects Wind?

[Badger N.H.]

I've been noticing that for decades.

It is fact. More often than not, the wind changes at the turn of the tide. It is so common that I have learned to wait for it.It is especially evident, in New England anyway, that if the wind is calm in the morning it will come at exactly the change of tide.Try it yourself. Look for it. It happens. It is fact. Maybe not everywhere or every tide but here on the East Coast it cannot be denied.

Atmospheric Stability

A change in water temperature associated with tide can affect the "stability" of the overlying atmosphere. Stability affects the transport of momentum (wind) from higher up to the surface. In a stable atmosphere, air parcels can't move vertically, therefore typically you'll have less wind. If the temperature profile is just right, even a small change in surface temperature could change the profile from stable to unstable and help "pull" the wind down.

Water Temperature Changes

I have noticed that there is usually more wind in the afternoon and this is because the land warms up. Often there is a change from the prevailing wind to a seabreeze. Many times during the summer there is a 180 degree shift from a light land breeze in the morning to a calm period thena seabreeze in the afternoon. But this has nothing to do with the tide. It is rare that you have a tide change at noon. Is the basic premise that cool water runs into the bay and changes the water temperature??? Does the wind change occur just after low tide or near high tide??? I believe that everything can affect the wind but it would seem that the huge amount of ocean surface and the huge amount of land surface would overwhelm the relatively small area of a bay.
