All sensors are based on actual readings. Based on experience, the sensor readings need slight adjustments to match conditions at the nearby kite beach.

Look at the sensor wind data and adjust as follows to get the actual conditions at the nearest beach.

(Point_Wells_Buoy sensor) - 10MPH = Richmond Beach
(West_Point sensor) / 1.5 = Golden Gardens / Richmond Beach
(Jetty_Island sensor) * 1.5 = Jetty Island
(Blue_Ridge sensor) red gusts reading = Carkeek Park
(520 bridge sensor) - 5MPH = Magnussen Park (it also reads ~20degrees off to the west)

WS Ferries are moving and therefore do not give accurate data

Strange but true: The SeaTac? and Arlington Municipal Airport readings are usually right on the money for wind conditions in the Sound.
