Where algae is most and least likely along the north coast over the next seven days, worked out from wave, sea-temperature and wind forecasts. An index of conditions, not a measurement of algae — how it works and what it can't tell you.
Not a health advisory. This is a hobby model built from public weather data, with no algae sampling anywhere in it. For bathing-water quality and any actual health guidance, use ARPAS Sardegna and your local Comune, who measure the water.
