Sargassum, so far, has appeared in significant quantities in 2011, 2015 and 2018. It has appeared in volume starting in the spring and running until early winter. Predicting 10 months away is nearly impossible.
I was there in June and July of 2017 and there was some sargassum but not an inordinate amount. My prior statement referenced very large amounts that were being tracked by marine biologists and oceanographers. There is going to be some, almost always, I was referencing the very large blooms that were inundating the Southern and Eastern Shores.
There is a little bit today here on Simpson Bay, and the surf is rough at times. Overnight the ocean came all the way up to BSV. It was very interesting to see.
