you can have a wide range of weather in july. dead calm to tropical waves. have had 3 waves in 10 days...gusts in low 40s, high 20s sustained. in these conditions it can get pretty sporty. if you sail out of oyster pond, see if you can get a pilot from sunsail or moorings. in big seas the entrance is tricky. watched 1 boat go on the reef....he wouldn't take a pilot.
