Coastal authorities in southern Spain are preparing for continued large-scale arrivals of invasive Japanese brown algae (Rugulopteryx okamurae) along the Andalucía coastline in 2026. Aggregated regional reporting indicates that around 40 municipalities may be affected to varying degrees, as marine currents continue to transport significant volumes of algae onto beaches.

The species, commonly known as Japanese brown algae or Asian invasive seaweed, has spread rapidly since its arrival in waters linked to the Strait of Gibraltar. It is now established along much of the southern Spanish coast, creating persistent challenges for local authorities responsible for beach maintenance and environmental management.

Tens of thousands of tonnes expected annually

Regional estimates suggest that approximately 56,500 tonnes of invasive algae could be deposited on Andalucía’s beaches during 2026. The figure is based on accumulated removal data and observed seasonal patterns rather than a fixed scientific forecast.

The distribution is uneven, with the highest concentrations typically recorded in Cádiz and Málaga provinces, particularly in coastal areas closest to the Strait of Gibraltar. Smaller but persistent accumulations are also recorded in Huelva, Granada and Almería.

Authorities describe the situation as continuous rather than seasonal, as the algae is repeatedly reintroduced by marine currents rather than arriving in single isolated events.

Around 40 municipalities affected across the coastline

Aggregated regional monitoring indicates that around 40 municipalities across Andalucía are affected to varying degrees. These include both large urban coastal centres and smaller towns dependent on seasonal tourism.

In Cádiz province, municipalities such as Algeciras, Tarifa, La Línea de la Concepción, Barbate, Conil de la Frontera, Bolonia, Caños de Meca and Rota have reported repeated beach accumulations. These areas are among the most exposed due to their proximity to the Strait of Gibraltar.. 

In Málaga province, the impact is concentrated along the western Costa del Sol corridor. The most consistently affected areas include Manilva, Casares Costa, Estepona, Marbella, Mijas Costa and Fuengirola. Occasional lighter deposits have also been recorded further east in Torremolinos and parts of the western Málaga city coastline have also experienced regular deposits requiring mechanical removal  depending on seasonal current conditions. 

Additional lower-intensity impacts have been recorded along parts of Granada, Almería and Huelva.

How the algae affects beaches

The arrival of Japanese brown algae can significantly alter beach conditions. When large volumes accumulate on shorelines, the algae forms thick mats that cover sand surfaces and shoreline edges.

Key impacts include:

  • Reduced usable beach area during peak accumulation periods 
  • Changes to the appearance and texture of sand, as algae mixes with sediment 
  • Odour issues as decomposing algae is exposed to heat and sunlight 
  • Increased labour requirements for mechanical and manual beach cleaning 
  • Temporary disruption to beach facilities in heavily affected zones 

While not structurally damaging to sand itself, repeated deposition can require frequent intervention to maintain safe and accessible beach environments.

What it means for beach goers

For visitors, the algae does not pose a direct health risk, but it can affect the overall beach experience.

In heavily affected areas, beachgoers may encounter:

  • Sections of shoreline covered in decomposing seaweed 
  • Reduced swimming and sunbathing space during peak accumulation 
  • Strong organic odours in hot weather conditions 
  • Increased presence of cleaning machinery during the day 

In many locations, municipalities prioritise clearing main swimming areas first, meaning conditions can vary significantly along the same stretch of coastline.

Despite these disruptions, beaches generally remain open, with local councils working to maintain accessibility throughout the tourist season.

Ongoing removal operations across Andalucía

Local authorities across Andalucía have implemented continuous removal programmes. These include mechanical beach cleaning, manual collection in environmentally sensitive areas, and transport of collected algae to authorised disposal sites.

In some municipalities, repeated interventions are required during peak accumulation periods. In more exposed locations, cleaning may take place daily in order to maintain beach usability.

The cost of these operations has placed pressure on municipal budgets, particularly in smaller coastal towns with limited seasonal revenue.

Environmental pressures and long-term management

Marine scientists continue to monitor the ecological impact of the Japanese brown algae.

Beyond its presence on beaches, Rugulopteryx okamurae has significant ecological consequences in coastal waters. The algae can form dense mats on the seabed, blocking light from reaching native marine vegetation and reducing the space available for local species to grow. This process can displace native algae and seagrass habitats, leading to reduced biodiversity in affected areas. Over time, the structure of local ecosystems may shift, with fewer native species able to compete for space and resources.

Marine scientists also note that the algae can alter seabed composition and simplify habitats used by fish and invertebrates. This reduces ecological complexity in nearshore waters and can affect local food chains. Once established, the species is extremely difficult to remove. Authorities and researchers generally agree that eradication is not currently feasible, and management efforts focus on containment and repeated removal rather than elimination.

Outlook for 2026

With continued inflows expected throughout 2026, municipalities across Andalucía’s coastline are likely to remain engaged in ongoing clean-up operations. While severity varies significantly by location, the overall trend indicates sustained pressure on coastal maintenance systems, particularly in the 40 municipalities identified as most affected.

Thousands of runners and spectators filled the streets of Palma on Saturday night as the sixth edition of the Binter NightRun turned the city centre into one of Mallorca’s biggest sporting events of the spring.

The popular night race returned to Palma on May 9 with illuminated routes, live music, DJs and entertainment points spread across the city, creating a festival atmosphere that continued late into the evening. Organisers described the event as one of Spain’s leading urban night races, attracting participants of all ages and abilities.

Three races brought runners through Palma’s landmarks

The event featured three different race formats designed to appeal to both experienced runners and families. The Green Family Mile, a charity-focused 1.7-kilometre route, began at the Dalt Murada esplanade beneath Palma Cathedral. The race was designed as an accessible and inclusive event encouraging participation from families and casual runners.

Later in the evening, participants took part in the 5K and 10K races through Palma’s historic centre and waterfront areas. The 5K route began near the Consolat de Mar on Passeig Sagrera, while the longer 10K race started at Bellver Castle before runners descended into the city centre under special lighting and entertainment effects. Large crowds gathered along the routes as runners passed some of Palma’s best-known landmarks including the Cathedral, the seafront promenade and the old city walls.

Music, lights and entertainment created festival atmosphere

Unlike a traditional road race, the Binter NightRun focused heavily on creating an entertainment experience for both runners and spectators. Throughout the evening, DJs, music stages and lighting installations animated the route while bars and terraces across Palma remained busy with visitors watching the race unfold. Organisers promoted the event as a combination of sport, tourism and nightlife, helping strengthen Palma’s growing reputation for large-scale urban sporting events.

Participants were encouraged to arrive early, with race bib collection taking place at El Corte Inglés Alexandre Rosselló throughout Friday and Saturday before the event.

Palma continued growing role in sports tourism

The Binter NightRun forms part of a wider race series held in several Spanish cities including Tenerife, Murcia, Zaragoza and Las Palmas. Palma’s edition has steadily expanded in recent years and is now considered one of the island’s standout sports tourism events. Earlier this year, the race was officially promoted at FITUR 2026 as part of Mallorca’s international tourism strategy.

For many runners, however, the appeal went beyond competition. The combination of illuminated streets, warm Mediterranean temperatures and a festive city atmosphere once again transformed Palma into a giant nighttime celebration of sport and community.

Police From France And Germany Join Patrols In Spain’s Granada Tourist Areas Under EU Scheme

Published

Police officers from France and Germany have begun joint patrols in tourist areas of Granada alongside Spain’s National Police as part of a European cooperation programme aimed at improving cross-border policing and visitor assistance.

The deployment forms part of the Comisarías Europeas 2026 (European Police Stations) initiative, which places foreign officers in selected Spanish cities during peak tourism periods. The scheme is designed to strengthen cooperation between European police forces and improve support for international visitors.

Under the arrangement, officers remain under the coordination of Spanish authorities but work visibly in mixed patrols in areas with high tourist activity.

Programme built on cross-border policing cooperation

The initiative is based on agreements between European Union member states that allow police forces to collaborate in public-facing roles during the tourist season. In Granada, officers from France and Germany are now working alongside Spanish National Police in areas with heavy visitor traffic, including parts of the city centre and key heritage locations.

Their presence is intended to complement existing policing rather than replace it, with Spanish officers maintaining operational control and decision-making responsibilities. The scheme has previously been used in other Spanish tourist destinations, particularly during periods of increased visitor numbers.

Focus on tourist areas and public assistance

The joint patrols are concentrated in areas with high footfall from international visitors, including historic districts and main cultural attractions. Officers are equipped to assist tourists directly, particularly in situations involving language barriers or basic security concerns such as theft prevention and reporting incidents.

While Spanish remains the primary working language of local policing, the presence of French and German officers allows for more immediate communication with visitors from those countries. The initiative also aims to improve visibility in busy public spaces, where pickpocketing and minor theft can increase during peak tourist periods.

What it means for tourists in Granada

For visitors, the most immediate impact is increased accessibility to police assistance in multiple languages. Tourists from France and Germany may find it easier to report incidents or seek help directly from officers who speak their language, reducing delays in communication.

The presence of mixed patrols is also intended to provide reassurance in high-traffic areas, particularly in locations such as the Alhambra surroundings, central squares and transport hubs where international visitors are concentrated. Authorities have stated that the goal is not to change policing methods but to improve communication and support in environments where language differences can slow down responses.

Impact on foreign residents

Foreign residents in Granada may also benefit from the initiative, particularly those from participating countries. The presence of French and German officers can make it easier to report non-emergency incidents or seek clarification on procedures without relying entirely on translation services.

However, the programme is limited in scope and time-bound, meaning it does not replace permanent policing structures or create dedicated foreign police units in the city. Instead, it is designed as a supplementary measure during periods of higher tourist activity.

Part of wider European security coordination

The deployment is part of a wider EU effort to improve operational cooperation between member state police forces, particularly in regions with high cross-border travel. Spain regularly participates in similar initiatives, especially during the summer season, when tourist numbers increase significantly across major destinations.

These arrangements are intended to improve coordination between agencies, share expertise and provide additional support in public-facing roles. In practice, officers remain bound by their national regulations while operating under the host country’s command structure.

Overlook

The introduction of French and German police officers into Granada’s tourist areas reflects a continued focus on managing international tourism through coordinated European policing efforts. For tourists, the most noticeable change is likely to be increased visibility of uniformed officers capable of communicating in multiple languages, particularly in busy central areas.

For foreign residents and visitors, the initiative may improve access to immediate assistance in familiar languages, although standard Spanish policing services remain unchanged. As Granada continues to attract high levels of international tourism, particularly in heritage and cultural districts, the programme forms part of a wider strategy to maintain public safety while improving communication between police and visitors from across Europe.
