With Orient if you go down to the clothing-optional section of the beach there typically is less seaweed. Not always, but most of the time. Mullet had zero sargassum the last time we were there in March. We were in Mexico in May and there were areas of sargassum here and there on the Riviera Maya, but it appears as if it has really taken off as the summer has progressed. Two years ago the beautiful beaches of Playa del Carmen were totally sea grass free when we visited. The seaweed is also a problem that we observed in the Mediterranean on the Balearic Islands of Spain (Mallorca, Ibiza and Minorca). Different strands of sea grasses, but just as annoying. But, over there it collected in specific pockets on the beaches and if you simply walked another 50 feet it would seaweed free. Not sure what's going on worldwide with this stuff, but could it be a combination of nutrients being dumped into the waterways combined with warming temperatures? That's my guess.
