It's much more like a beach along the Eastern seaboard than a typical Nor Cal beach. The spit runs along the coast for over a mile and the sand is covered with dune grass like that lining the beaches of Carolina. Yes indeed, Limantour is a very unique windsurfing experience. When it happens Limitour has a fairly long season, with good windsurfing from March to September. It can get very, very windy at Limitour, especially in the Spring.
Summer tends to be a bit lighter winds and less consistent that Spring.
And late Summer tends to have the lightest wind, but some of the best swell activity. Limantour often has a local wind caused by the fog build-up in Bodega Bay. On such days you can see the fog hugging the coast to the north and to the south, but Limitour will have a pocket of sunshine and plenty of wind too. Limantour is not a place for beginners. In fact, it is best suited for upper-intermediate to advanced sailors.
