Which way it faces

Faces east, open to the Atlantic.

Beaches open to the sea on that side are usually the first to collect seaweed when it arrives.

Questions

Is there seaweed at Palm Beach right now?
Satellites cannot see the sand, so nobody can say from this data alone. As of November 12, 2026, NOAA rates the risk for the coast around Palm Beach as low. That is about sargassum offshore that could come in.
Which months are worst for seaweed around Palm Beach?
In NOAA's daily record since July 2025, the months with the most medium or high days for this coast were August 2026 (30 of 30 days), July 2026 (28 of 30 days) and September 2025 (26 of 30 days). July 2025, August 2025, December 2025 and January 2026 and others had none.
Does it matter which way Palm Beach faces?
Palm Beach faces east, onto the Atlantic. Beaches open to the sea on that side are usually the first to collect seaweed when it arrives.
Where does the level come from?
From NOAA's Sargassum Inundation Risk map, which NOAA publishes daily and labels experimental. NOAA scores the shoreline in long runs. On that day this beach sat in a run of about 172 km with one level for all of it. A beach and its neighbour can share a level and still look different on the ground.
How often does this page change?
Once a day, by itself, after NOAA posts its map. NOAA's map runs one to two days behind the calendar, so the page always shows the date of the data it is quoting.

The level comes from NOAA’s daily Sargassum Inundation Risk product, which NOAA calls experimental, not a forecast. NOAA scores the shoreline in long runs. On that day this beach sat in a run of about 172 km with one level for all of it. Low is the bottom of NOAA's four levels: its satellites found little floating sargassum in the waters off this coast over the past week.
