Spanish coastal authorities tackle algae outbreaks and water contamination on beaches

Municipal crews in Cádiz removed invasive Asian algae (Rugulopteryx okamurae) from the beaches of Santa María del Mar and La Victoria after recent wind‑driven accumulations, while La Caleta required no action. The cleanup was timed with low tide and reduced beach use to minimise disruption.

In the Valencian town of Port Saplaya, two sections of the north and south shoreline remain closed to swimmers because of short‑duration microbial contamination. Local officials await water‑quality reports and plan infrastructure upgrades to address recurring sewage inputs from nearby irrigation channels.

Both incidents illustrate ongoing coastal‑environment challenges in Spain, prompting municipal governments to intervene to protect public health and preserve beach tourism.
