In Evia, Greece, the sea off Daphni Beach — just outside Chalkida — has taken on an unusual appearance due to a significant increase in jellyfish populations. According to reporting by Evima, large numbers of jellyfish have recently been observed in deeper waters offshore, though not yet close to the shoreline.
A Seasonal Phenomenon
Local spearfishers confirm the sighting, and a widely shared photo shows what appear to be countless jellyfish drifting in the water. So far, their presence remains largely offshore, limiting direct contact with swimmers. Still, concerns are rising as the summer tourism season heats up and approaches its peak.
Monitoring Conditions
Experts stress that such blooms are common seasonal occurrences, often linked to rising sea temperatures, ocean currents, and abundant plankton — a key food source for jellyfish. While no stings have been reported at Daphni Beach to date, local authorities and residents are urging caution, especially for those swimming farther from shore. Changing wind patterns or currents could shift the jellyfish closer to the coast in the coming days.
