Damn. Can't find out who wrote that...

Twas me.

It is my understanding that sea breezes are essentially a local
phenomenon and would not effect either off shore or inland wind farms.
It is quite possible that there is a statistically significant pattern
to wind but looking at the wind speed record from my weather station
over the last few weeks it is not immediately obvious.
