Weather in the summer can be 90+°F with water temperatures warm enough for boardshorts only in July and August. Shorties come in for June and September. Full wetsuits the rest of the year. Winters are not really kite-able here, with the bitter, blustering Easterly winds bringing snow, hail, and rain.
Spring: March to May, light winds 12-20, somewhat finicky. Summer: June to early September, windy, 15-35, pretty solid. Fall: September to October, light to moderate winds, but very steady: 13-25. Clean, solid wind. Main direction westerlies. Works in NW, W.
