What is the windsurfing season in the Columbia River Gorge?
Early season starts in April or early May and lasts through August. West wind is most common with many windy days. Late season starts in September and goes through November with West and East wind days and more no wind days. Windsight has provided some data on sailable days for the year 1994. A sailable day is defined by them as a day that contained a 3 hour time period where the one minute wind speed average was 15 MPH or greater. This calculation does not include wind gusts. For a day to be considered sailable there only had to be one place on the river that met the above specifications. This means that there could have been sailing from Rooster Rock in the West to Arlington in the East or anywhere in between. East wind days were included which helped the numbers for March and November.
