How waves are estimated

Significant wave height from the forecast hourly wind and the open-water distance (fetch) upwind, using the SMB method (US Army Corps of Engineers Shore Protection Manual, 1984), rounded up to the next 0.1 m. It is not a measurement: gusts, leftover swell and shoals can make water rougher. Under 0.2 m: calm; 0.2–0.5 m: choppy; over 0.5 m: rough.

Water

Trophic status from the latest monitoring: eutrophic.

Clarity was measured with a Secchi disk in 19 years between 2004 and 2025; the latest annual mean is 1.8 m.
