"Mini tsunamis", known locally as rissagues, struck the Balearic island of Ibiza on Monday morning, sending seawater surging through streets and restaurants at the popular Platja de s'Arenal beach in Sant Antoni de Portmany. Holidaymakers and locals fled as the sudden change in sea level flooded the promenade, and San Antonio Town Hall cancelled a concert tribute due to take place there that evening "for security reasons" after the stage and event equipment were swamped.

The phenomenon, caused by rapid atmospheric pressure changes rather than seismic activity, also affected ports in Majorca including Alcudia, Andratx, Soller and Port Adriano near Magaluf, with holidaymakers in Puerto Alcudia wading through floodwater on the promenade. The first surge hit Ibiza just before 8am, with sea levels recorded rising by 86cm (2.8ft), while Ciutadella in Menorca was placed on standby for oscillations of up to four feet (1.2 metres) until midnight. No injuries were reported, and similar events have previously hit the islands, including a 2018 episode that reached five feet and dragged boats out to sea.
