Is there seaweed on Aruba tomorrow?
Tomorrow, NOAA's satellite risk for Aruba is medium at 7 beaches, low at 4 beaches (data of Mon 5 Oct 2026). Aruba's west and south coasts are in the lee of the trade wind: calm, clear water most days. The north and east coasts take the wind and the swell head-on and are for looking, not swimming.
Tomorrow: 0 of the 1 beaches facing the east half of the compass (north-east to south-east) and 7 of the 10 facing the west half have a medium or high risk. Sargassum drifts in from the open Atlantic on the trade wind and the current, so a coast that faces east usually gets it first; NOAA's risk is worked out from the seaweed within 50–100 km of each stretch of coast and does not know which way a beach faces.

How to read NOAA's risk
NOAA's Sargassum Inundation Risk is an experimental product of NOAA/AOML, NOAA CoastWatch/OceanWatch and the University of South Florida. Every day it compares the floating seaweed that satellites see within 50–100 km of each stretch of coast with the weeks before, and gives the stretch one of four classes. We show them as three words:
- Low (NOAA: low): little or no seaweed near this coast.
- Medium (NOAA: warning or medium): seaweed at sea nearby; some may wash up, depending on wind and current.
- High (NOAA: high): a lot of seaweed nearby; expect it on the beach and brown water at the edge.
- No data: clouds or no coast segment near the beach; we do not guess.
What it cannot tell you: whether a hotel cleaned its beach this morning, or a raft that arrived overnight. It looks at stretches of coast of a few kilometres, not at one beach. Seaweed on the beach is not dangerous to touch, but rotting piles give off hydrogen sulphide (the smell of rotten eggs), which can bother people with asthma.
