Jellyfish Alert in Playas de Rosarito

Playas de Rosarito is on high alert due to a sudden influx of jellyfish, prompting local authorities to warn beachgoers about the potential for painful stings. Aaron González Casillas, who coordinates the aquatic rescue unit, reported spotting hundreds of Velella velella jellyfish washed up along the shoreline late Saturday afternoon, April 27, as the tide receded.

So far, there has been one incident involving a four-year-old boy who suffered a jellyfish sting but was quickly treated with oxygen and clean water rinses by the staff. Paramedics from the Red Cross also attended to him promptly. The child received immediate care, highlighting the potential dangers these marine creatures can pose, especially to those with allergies, as stings can cause severe respiratory reactions.

The jellyfish identified in this occurrence is commonly known as the ‘sea raft,’ or ‘by-the-wind sailor,’ a species familiar to the area but appearing earlier than usual this year; they typically start showing up in May and last about a week. Another variety known as “agua mala,” recognized for its bubble-like body with tentacles, tends to appear during July and August.

Casillas explained that the presence of these jellyfish is linked to climate change and shifting ocean currents from the north and south. Once ashore, jellyfish have a very short lifespan—approximately four minutes.

For safety, people are currently advised only to enter the water up to waist depth due to strong currents and dangerous underwater pits. Additional safety tips from authorities include avoiding contact with jellyfish. If contact occurs, it’s important to wash the affected area with salt water and seek medical attention immediately. Special care should be taken to protect children from potential harm.
