Purple jellyfish has moved away from the Saronic Gulf and the beaches of Athens and Attica and the nearby islands during the week July 1-10, 2022 and it has now made its presence visible in the Cyclades islands. According to the JellyReport about the presence of jellyfish in Greece published on Sunday, July 10, 2022, it was the strong northern winds that caused the movement of the jellyfish population.
JellyReport is based on registrations/observations at inaturalist online platform July 1-10, 2022
Based on the wind forecast in the week July 11-17, it is highly possible that the north winds will sweep the purple jellyfish more to the South, and will possibly move away from the Cyclades islands in the Aegean Sea and from Corfu in the Ionian Sea, noted the Greek Biodiversity Watch.
It should be noted that winds change directions during the day and night.
Next to the winds, however, another factor are the sea currents locally. It always depends on the local sea currents of each area as to where the jellyfish will move.
The JellyReport is published every Sunday with useful information on jellyfish sightings for the month we are in and specifically for the last ten days, for the upcoming weather conditions for the next week, but also other information concerning jellyfish in general.
For correct information, citizens are invited to upload their recordings to iNaturalist via the website: https://www.inaturalist.org/observations/upload or the corresponding application “iNaturalist” available for android and ios mobile phones.
Citizens are asked when they see jellyfish (regardless of what species) to take 1-2 minutes to upload the jellyfish recordings to iNaturalist (https://www.inaturalist.org/observations/upload) so that this way for citizens to be informed about the presence of jellyfish, but also for the monitoring of the phenomenon of outbreaks and appearances.
