This isn’t a factual explanation, for sure, but what the heck!
We’ve known the island to experience sargassum during both our April and November recent trips but I’m inclined to think it’s more about ocean and tidal conditions at any given time rather than time of year.
But the good thing is, if it’s crazy with sargassum on one side of the island we find heading to beaches on the exact opposite directions will usually see the problem disappear completely.
Where we stay at BSV on Simpson Bay the staff is always out there early raking it up and carting it away so if you’re a real slug-a-bug you might not even know there was any there in the first place. They are the best!!
And on another note, over almost fifty years of visiting the island we’ve never seen it on Mullet Bay Beach and yet I’ve read others relating how Mullet was buried in the stuff. Glad we never saw that……😊😊
