Our newest NOAA observation is too old to stand behind, so we hold the level back rather than pass it off as current.
Head to head editorial
St. Lucia: east coast vs west coast sargassum
Book west for calmer water: Rodney Bay and the leeward shore face away from the open Atlantic, while the east coast catches it head on.
The reasoning
Why the map says what it says
St. Lucia is one island with two different seaweed stories, and most visitors already stay on the sheltered side without knowing that is why the water looks the way it does. The east coast card below tracks the exposed Atlantic shore, which is wilder in every sense. If a property lists an east-coast address, check that card, not the west one, and ask the hotel which shore its beach actually sits on.

The record
November, five years back satellite-derived
Raw satellite floating-algae detections near each coast for this month in each of the past five years (brighter orange and red = stronger signal). These are detections, not risk ratings: clouds and glare can hide algae, offshore mats do not always land, and the nearshore strip is blanked where the signal is unreliable.

Making the call
How to decide
- Read the cards above, including the full mix of levels, not just the headline.
- Open a beach cam for each contender if one exists; nothing beats looking.
- Ask each hotel for a same-day photo of its swimming beach.
- Remember the atlas rates coastlines, not resorts: one cove can beat its neighbor on the same morning.
