Low · 28/100

Low peak drift risk around Wed 07:00.

warm water supports seasonal jellyfish activity; surface drift/current is noticeable; local shoreline exposure is not mapped yet.

Sightings override the model: if you see small purple jellyfish with long trailing tentacles, treat them as sting-capable and give them space.

Scoring methodology (for technical users)

We score each hour from 0 to 1 using daylight and these weighted components:

Wave height (35%): best below 0.36m, then decreases as it rises.
Wind speed (25%): best below 5.4m/s, lower is better.
Sea surface temperature (15%): best within 20.6°C to 30.4°C.
Tide and currents (15%): best around slack/high-tide windows.
Daylight (10%): visibility is better in daylight, so night hours score lower.
