Sargassum at Sandspur Beach, Bahia Honda State Park
First bulletin for this beach lands with tomorrow morning’s update.
Sandspur Beach is the ocean-side strand of Bahia Honda State Park, on Big Pine Key in the Florida Keys. This page gathers what you need before a visit: the sargassum reading taken this morning, a rating from 0 to 5, and a map that compares Sandspur Beach with the other Keys spots we track.
Because the report is rebuilt every morning, you learn about a heavy wrack line before you pay at the park gate rather than after. The recent trend sits next to today's figure, so you can tell whether an episode is building or fading, which is what usually decides a snorkelling plan.

What to know about this beach
Facing south-east, Sandspur takes the prevailing wind head on. The trades that blow across the Keys for much of the year come from that exact quarter, and they carry sargassum rafts drifting up from the Caribbean along the reef tract straight at this shoreline. Exposure here is direct rather than glancing, which is why the ocean side of the park often shows a wrack line when sheltered beaches nearby do not.
The shape of the shore matters too. The strand is long and open, with no headland to trap drifting weed, so an arrival tends to spread thinly along the sand instead of piling into one corner. The park's Gulf-side beach lies a few minutes away on foot and sits on the sheltered face of the key, so the two shores can read very differently on the same morning.
Frequently asked questions
Is Sandspur Beach more exposed than the rest of the park?
Yes. It is the ocean-facing shore, and its south-easterly aspect looks straight into the prevailing trade winds that push sargassum along the reef line. The Gulf-side beach across the key is far more sheltered.
How do I check Sandspur Beach before I go?
Look at the FanGass map on the morning of your visit. Sandspur Beach carries a rating from 0 to 5, refreshed daily, together with the previous days so you can see whether the episode is growing.
Can a single day of wind change the beach?
Clearly. A settled easterly or south-easterly flow drives rafts onto this aspect within hours, while a northerly behind a cold front usually pulls the floating weed back away from the ocean shore.
Is there a backup beach inside the park?
Calusa Beach sits on the Gulf side of the same park, a short walk away and out of the direct easterly drift. Both beaches are tracked separately on the FanGass map.
