About St. Lucia Beaches

Conditions are good today. Seaweed levels are low and the water is clear. No significant concerns.

Geography & Why It Matters

St. Lucia is a volcanic island in the eastern Caribbean. The west coast: facing the Caribbean Sea: is calm and sheltered. The east coast faces the Atlantic and sees more wave action and occasional sargassum.

Seaweed & Sargassum at St. Lucia

St. Lucia's west coast beaches (Reduit, Marigot Bay, Anse Chastanet) stay relatively clear of sargassum due to their sheltered position. The east coast sees more exposure. Overall, St. Lucia has lower sargassum risk than Mexico's coast or Punta Cana.

๐Ÿ“œ Coastal History

St. Lucia changed hands between Britain and France fourteen times: more than any other Caribbean island: earning it the nickname 'Helen of the West Indies' for being so endlessly fought over. The twin Piton mountains rising dramatically from the sea were landmarks used by sailors navigating the southern Caribbean for centuries, and the natural harbor at Castries was one of the most strategically important in the Eastern Caribbean during the age of sail. St. Lucia has produced two Nobel Prize laureates: more per capita than any country on Earth: including poet and playwright Derek Walcott, whose epic poem 'Omeros' reimagines Homer's Odyssey on the waters and shores of the Caribbean.

"He rules the swelling of the sea; when its waves rise, you still them.": Psalm 89:9
