Share a past sighting
If you saw jellyfish or were stung on a Thai beach before, mark the beach and the date: the exact day, or at least the month and year. Past sightings help describe the jellyfish season of each area more precisely.
Why it helps
- The jellyfish season of an area is described from many years of observations. The more dated cases, the clearer which months see more jellyfish.
- Past sightings do not change today’s forecast. To report jellyfish right now, use the regular form.
- We do not ask for your name or contact details.
