Latest incidents

A visible microalgae patch was reported in the bathing area of Los Charcos de Valleseco and along the nearby Anaga coastline. The event was associated with a natural microalgae bloom rather than a confirmed sewage discharge.

Bathing reopened later the same day after authorities resolved the incident. The initially suspected hydrocarbon spill was ruled out and was linked instead to an incident involving an inert-gas production system on a vessel.

Bathing was preventively prohibited across the Valleseco coastline after an incident initially reported as a possible marine discharge of unknown origin.

The bathing area returned to operation with a yellow flag. The municipality reported a small surface oil patch likely related to sea conditions, while no bathing prohibition was issued by the health authority following routine sampling.

Bathing was temporarily prohibited after dead fish, oil and floating marine debris were observed in the bathing area. Samples were taken to assess water quality and the material present.

A visible white patch was reported in the water at Las Teresitas and attracted the attention of bathers. The event was reported by local media.

The affected section reopened after follow-up analyses returned normal bathing-water values.

A section of Las Teresitas was temporarily closed to bathing after routine monitoring detected a short-duration water-contamination episode.

El Bloque and Los Charcos reopened on 18 September after follow-up analyses returned favourable values and normal parameters.

Santa Cruz de Tenerife City Council prohibited bathing at El Bloque and Los Charcos in Valleseco after routine monitoring detected indicators of water contamination at both bathing areas.

The affected section of Las Teresitas reopened after follow-up analyses returned normal bathing-water parameters.

Bathing was temporarily prohibited in the central section of Las Teresitas around access 8 after routine monitoring detected abnormal contamination parameters. The episode was classified as short-duration contamination.

A large brown patch was observed along the Valleseco coastline, particularly around El Bloque and Acapulco. According to reporting, the Santa Cruz de Tenerife municipal emergency coordination centre (CECOPAL) raised a red flag and advised against bathing on 12 August 2023 after microalgae and hydrocarbon residues were detected in the area. Reporting two days later still described the red flag at both bathing areas. No official reopening date has been located, so MiCharco keeps this episode as historical and not as a restriction currently in force.
