Sargassum seaweed has begun washing up on the Kingston seawall and creating a stench as it decomposes.
The entire Caribbean has been bracing for the arrival of a large mass of the seaweed which has been described as record-breaking.
Caribbean tourism economies have been trying to take mitigatory measures against the annual migration.
Photos taken by nature group, Seawalls and Beyond Volunteers showed decomposing and fresh deposits along the Kingston seawall and stretching east. The sargassum is expected to affect significant sections of the Guyana coast.
Sargassum is part of the genus of large brown seaweed (a type of algae) that floats in island-like masses and never attaches to the seafloor.
According to scientists, the sargassum has flourished in recent years due to the combination of an increase in nutrient runoff from the Amazon River and changing water temperatures.
In March, the Caribbean Hotel and Tourism Association listed the sargassum as a major concern of operators in the industry.
