I almost hate to look at weather forecasts given the miserable wind conditions at the worlds, but here goes. Source for the info is iwindsurf.com, a subscription service that has a data station at Stevenson, Washington, almost directly across from the Cascade Locks area. The link gives the forecast for today, with a discussion by a meteorologist. Generally not bad.
So how about Wednesday, Thursday and Friday? Here's the extended discussion. Not so hot (or, maybe too hot!) Let's hope things normalize by the time the Nationals start!
Lastly, for what it's worth, some windgraphs of the observations at Stevenson for the past eleven days, starting with August 1 on top and ending with August 11 on the bottom. They is what they is, and we sail in what we got, not what we want. Enjoy!
