When the seaweed comes, what it actually means for your vacation — and the plan that keeps your water days perfect regardless.
Sargassum is a free-floating brown seaweed that drifts across the Atlantic and, in some months, washes onto Caribbean shorelines — Tulum included. It's natural, harmless to people, and maddeningly unpredictable: the same beach can be covered on Tuesday and postcard-perfect on Friday.
The season: roughly April through October, peaking in late spring and summer. November to March is generally clear. But "season" is a tendency, not a schedule — plenty of July weeks are pristine, and the daily picture depends on wind and currents.
The good news: Tulum is the best-equipped destination in the Caribbean for seaweed days, because its most beautiful water was never only on the beach.
