When is Sargassum season?

Sargassum season runs from March through October, and Sargassum now aggregates almost every year, starting January/February in a massive belt north of the Equator. During the late winter and early spring months, Sargassum moves northward due to seasonal winds and currents. Later, in late spring and summer, this Sargassum belt may stretch across large portions of the Atlantic Ocean and drift into the Caribbean Sea and Gulf of Mexico via the North Equatorial and Caribbean current systems.
