The sargassum forecast continues to be poor for the next while, particularly east-facing beaches. Just be prepared and willing to head to beaches on the opposite side of the island from the problem areas if needed. This is translated text from the latest forecast for SXM:
"Forecasts for the next 4 days
The invasion continues from the east.
A veil of altitude clouds slightly masks the last images analyzed. Those (images from May) 30 show more clearly the situation.
The northern rim is loaded with algae. The sea, east of the islands, remains equally loaded.
Arrivals concern all coastlines exposed to eastward flux and bypassing effects. They are more or less repetitive, or even locally continuous.
No lull in sight at the moment.
Trend for the next 2 weeks
The ongoing strandings will continue.
The Atlantic remains loaded with sargassum, which continues to proliferate."
