Prevailing winds are north, so it will be a battle between them and the DC thermal. I think 9/18 is possible today between 2 and 5 pm.
Air temps around 55 degrees. Could be good foiling if you have the proper rubber gear for a very cool but sunny day.
Tomorrow, similar condition, but partly cloudy, and slightly
Lighter winds make for foils only.
Sunday looks like Saturday.
