Environmental estimate

Conditions less favourable for jellyfish arrival

Forecast wind and the regional coastline orientation are less favourable for jellyfish transport towards the shore. This is a limited-confidence regional physical indicator; it does not confirm the presence or absence of jellyfish at this beach.
