Outlook of 2024 Sargassum blooms ( November 30, 2024)

In most previous years, November – December are the months with minimal Sargassum, and this year appears to be no exception. Specifically, in December 2024 the Caribbean Sea and the Gulf of Mexico (including Florida) will continue to be Sargassum free. The western and eastern Atlantic regions may see slightly increased Sargassum, but month-to-month fluctuations may also occur due to multiple factors. On the other hand, if the total amount of Sargassum int he eastern Atlantic continued to remain at historical record levels in the next 1-2 months, then 2025may be another major Sargassum year.
