It’s unknown how a lot sargassum will wash ashore on South Florida’s coasts. Nonetheless, in response to historic information, it’s anticipated that probably the most affected areas embody the Keys and the stretch that goes from Miami to Jacksonville.
These areas can be largely sargassum-free till the tip of Might, in response to reviews.
In March, scientists noticed solely 75 % of the quantity of sargassum seen in the identical month final 12 months. It’s a constructive quantity however nonetheless very excessive.
“Not like most earlier years, whole sargassum quantity decreased from about 9 million metric tons in February to about 6.5 million metric tons in March,” reads a report from USF’s Optical Oceanography lab.
“The whole quantity in March was nonetheless above 75% of all earlier March months, indicating 2024 might nonetheless be a serious sargassum 12 months,” they concluded.
International locations like Mexico and the Dominican Republic have began to report a rise within the arrival of the alga after months of having fun with small portions of it.
Mexico needed to elevate its sargassum alert to “Stage Two,” because the nation has seen a spike in seaweed in Cancun and close by cities.
As per native forecasts, Playa del Carmen alone can be receiving as much as 300 tones per day over the following few weeks.
For its half, Dominican Republic seashores have reported an increase in sargassum since two weeks in the past.
Most Caribbean nations additionally struggling the ravages of this phenomenon have opted to spend money on vessels outfitted with particular expertise to gather the seaweed within the open sea. In the US, such an possibility is at present prohibited, as sargassum offers shelter for marine species.
Florida has employed specialised staff who clear seashores twice per week utilizing heavy equipment however solely the place turtles could nest.
Consequently, native communities are on the verge of seeing main losses in tourism income.
“Economically, a “extreme” sargassum occasion might have greater than a $20 million impression in simply the Keys alone,” stated FAU analysis professor Brian Lapointe.
Sargassum Season in 2023 and Forecast for 2024
A number of authorities have expressed that this 12 months, sargassum season won’t be as onerous because it was in 2023. But it surely’ll be related.
As an example, in nations like Mexico the season formally began on the finish of March, whereas final 12 months, seashores have been lined with seaweed by the tip of January.

In December 2023, the scale of the bloom broke information which is a telltale signal that this 12 months we’ll additionally see an necessary arrival.
“This [satellite observations made in December] signifies that 2024 can be one other main Sargassum 12 months,” USF sargassum tutorial specialists published in January.
