Sargassum at Playa San Rafael (Barahona): today's report

Today, September 1

Light

Some weed

Playa San Rafael lies along the coastal road running south from Barahona towards Paraíso, at the foot of the Sierra de Bahoruco. A mountain river reaches the shore here and pools into freshwater basins just behind the beach, in the south-west of the Dominican Republic.

What you get on this page is the sargassum situation at Playa San Rafael for today, condensed into a 0 to 5 rating, plus a map showing the beach among the other spots of the Barahona and Pedernales stretch. It is reviewed each morning, so the reading tracks the day you are actually going.

What to know about this beach

The water here is the Caribbean Sea and the beach looks south-east. Sargassum reaching the region has crossed the Atlantic on the trade winds and then travelled the full length of the island's southern shore. By the time rafts get this far west they are broken up, so the south-west sees irregular pulses rather than the continuous belts that pile onto eastern coasts.

The shape of the shoreline does the rest. Between Barahona and Paraíso the Sierra de Bahoruco drops almost straight into the sea, the bottom deepens quickly, and San Rafael is a pebble shore rather than fine sand. There is little shallow ground for weed to settle on, and swell often takes back what it delivered. The small enclosed coves along this road are the exception: they hold material longer than the open coastline.

Frequently asked questions

Why does Playa San Rafael get less sargassum than the east?

It sits on the Caribbean side facing south-east, at the far end of the drift route. Rafts arriving from the Atlantic have already broken apart, so this coast sees short pulses instead of continuous mats.

How can I check conditions on the day?

The FanGass map publishes a 0 to 5 rating for Playa San Rafael every morning. Check it before you take the coastal road, since conditions along this shore can change from one day to the next.

Do the freshwater pools get affected?

No. The basins fed by the river sit behind the shoreline and stay out of reach of the seaweed. A stranding affects the sea bathing area only, not the pools inland of it.

Which nearby beaches are worth comparing?

Los Patos, a few kilometres further south on the same road, and the Pedernales beaches appear on the same map. Strandings rarely spread evenly here, so ratings often differ within a short drive.

Methodology & transparency — FanGass is a free service published by the Katchak agency and created by Morgan Haillus. Every morning, each beach’s 0-to-5 score is recomputed by cross-checking official bulletins (Météo-France, NOAA, University of South Florida), satellite imagery of the offshore rafts, and on-the-ground user reports.
