tomorrow at the coast

I’ve seen this phenomenon before, in the summer at the coast.

If you looked at xc weather you could be mistaken for thinking it will be on at Crimdon tomorrow, I could be wrong but I recon it will be light and off to the north. The RASP screen shot predicts light winds at the coast (6mph) but more than double that just out to sea and the same only a few miles inland.

Where the wind meets the land at 90 degrees it seems the effect most pronounced, if there is an angle then the wind is deflected. It appears to be a very localised effect.

Anybody got any explanation of what’s happening.

I am sure it is something to do with a sea breaze fighting against the trues wind when it is north east used to see it so often when I used to kite surf and could see the cloud hoofing along above us and nothing right on the coast. its called the calma wind and is produced by pilots that cant get out and help to produce this
