sargassum in caye caulker
Live forecast, seasonal pattern, and where the water stays clean · updated for 2026
The short answer
Caye Caulker's main swim spot, The Split, sits on the island's north/west corner and usually stays clean; the east-facing shore collects seaweed in peak months (June-August).

The full picture
How sargassum actually plays out in Caye Caulker
Caye Caulker is small enough that sargassum is a five-minute problem: if the east shore has seaweed, you walk to The Split, the channel-side swimming spot at the island's north end, where the current keeps the water clear most of the season. The village's west side and the back-side docks likewise face away from the incoming rafts.
The east-facing shoreline, including the stretch south of the village, does collect sargassum in the peak months, and the island's cleanup is more village-scale than resort-scale: expect it rawer than San Pedro's raked resort sand. The reef trips, which are the reason most people come, run normally: Hol Chan, the local channel snorkels, and dive trips are unaffected.

Sargassum in Caye Caulker: FAQs
Is there sargassum in Caye Caulker right now?
Check the live forecast band on this page for the Belize Met Service's current outlook and the satellite map for what's offshore. Seasonally: November-February is essentially clear; June-August brings accumulation to the east-facing shore, while The Split usually stays swimmable.
Is The Split affected by sargassum?
Usually not. The Split sits at the island's north end on the channel, where current keeps floating seaweed moving. It's the reliable swim spot even in peak months. Expect it busier then for exactly that reason.
Is Caye Caulker better or worse than San Pedro for sargassum?
Similar exposure, different handling: both islands' east shores receive seaweed in season. San Pedro's resorts rake daily; Caye Caulker's cleanup is village-scale, but The Split gives it a reliably clean swim that doesn't depend on raking.
Do the snorkel trips still run during sargassum season?
Yes. Sargassum is a shoreline issue: Hol Chan, the channel snorkels, and dive sites are unaffected and trips run normally through the season.
