How this is ranked

Seaweed risk is the share of weeks in that month, 2016–2024, when NOAA AOML's satellite sargassum signal (the Alternative Floating Algae Index, developed at the University of South Florida) within about 20 km of a beach's stretch of coast was in the top fifth of the whole record, smoothed over neighboring weeks and adjusted for how exposed each beach is. A destination's figure is its median beach. It is the same history Veabird's sargassum model learns from; download it as an open dataset (CSV and JSON, CC BY 4.0). Sea temperature and rainy days (at least 1 mm) are 6-year ERA5 averages (Open-Meteo) for the destination's resorts; storm risk is Veabird's year-ahead outlook from historical storm tracks.

Limits: this is history, not a forecast. Blooms vary a lot from year to year, clouds hide the sea in some weeks, the satellite sees seaweed offshore rather than on the sand, and murky coastal water can read as seaweed near river mouths and shallow banks. Cleanup crews and barriers change what you see on a given beach. ERA5 counts light showers, so rainy days can run high on dry islands. Check the live forecast before you go.
