I was wondering what methods people here use for their wind forcasts? Who do you find most accurate? I personally use 3. Wunderground, The Weather Channel, and the most lately, Sailflo.com. In my opinion Sailflo has been the best, although not perfect (I should try to fully grasp the meaning of prediction in relation to atmospheric science). I have found them to update their predictions accurately, timely, and yet sometimes radically. They categorize geographically, then subcategorize by specific lakes / beaches. I really like that.

I use a combination of sailflow.com and wunderground.com. Sailflow seems to frequently forecast about 60% high for my area, but like you said, they are good about updating their forecasts. Weather underground is usually more accurate where I live.
