Just returned from Okaloosa Island last night and the seaweed (June Grass as the locals call it) was terrible. Worse at the end of the week then it was at the start, which was pretty bad. The whole beach from Destin to the El Matador effected(only places we checked)....a couple spots amazingly bad with the beach green with seaweed!
Weather was perfect.....beaches looked great (though recently renourished not as bleached white as yet), but missed those clear emerald waters. Going to Myrtle Beach in August and there won't be any clear water overthere.
Had a good time though.....very peaceful, relaxing in the FWB/Okaloosa Island area.
