Disappearing Wind

We haven't had much wind for a while now. The forecasts from Wind Guru and Buoy Weather keep promising strong winds in the near future and then change the forecast when the time gets closer. Once in a while a few of us get out for an hour or two but usually a bit underpowered. Yesterday there wasn't a breath of air. It was so still it was a bit spooky at the beach. Today the wind couldn't get much over 10 knots. Tomorrow should be better according to the predictions. They have been calling for a few days of really strong winds next week and then this morning they changed the forecast to almost no wind for the whole week. The only chance looks like tomorrow and Sunday. Water is still fairly warm and it is almost Thanksgiving - what's going on?
