Unusual Swarms of Saharan Locusts in the Canary Islands: What You Need to Know

Unusual swarms of Saharan locusts have recently reached the eastern Canary Islands, casting a hazy shadow over popular destinations like Lanzarote, Tenerife, Gran Canaria, and Fuerteventura. This phenomenon has raised questions among holidaymakers about what it means for their planned trips. Let’s dive into the details of this unusual event.

What Is Happening in the Canary Islands Now

In the past week, large swarms of locusts have been reported across Lanzarote, Fuerteventura, Gran Canaria, and Tenerife. Local media and residents have shared striking images of hazy, insect-filled skies, particularly over rural and semi-desert areas. This unusual sight contrasts sharply with the typically clear skies of the Atlantic archipelago.

Meteorologists explain that these locusts originated in North Africa and were transported across the ocean by strong Saharan winds. This airflow, which often brings calima—a dust haze from the Sahara—has also acted as a highway for the locusts, concentrating them over the easternmost islands where the winds first make landfall.

Regional agricultural groups emphasize that this wave resembles a migratory overflight rather than a full-blown agricultural plague. Officials note that the locusts have arrived in a weakened state after their long sea crossing and are not currently exhibiting the dense ground coverage or crop destruction typically associated with major locust crises in mainland Africa.

Authorities on the islands are on high alert but have not initiated any evacuations, closed major tourist zones, or altered the overall safety status of the destination. Flights, ferries, and primary resort operations continue to function normally.

Health, Safety, and Daily Life for Visitors

For most travelers, the primary impact of the locust swarms is more of a nuisance than a danger. Locusts do not sting, carry venom, or transmit diseases like mosquitoes do. Visitors are more likely to experience discomfort from insects colliding with them outdoors or collecting on balconies, poolsides, and windshields.

Health specialists on the islands advise that individuals with asthma, dust sensitivity, or strong insect phobias may feel the effects more acutely, especially when locusts coincide with calima conditions that can already reduce air quality. Simple precautions can help mitigate discomfort: limit outdoor exertion during windy periods, keep hotel windows closed, and consider wearing masks or sunglasses if the air feels irritating.

Currently, there are no special vaccination, medication, or quarantine requirements related to the locust swarms. Standard travel health advice for the Canary Islands still applies, including sun protection, hydration, and routine care for minor scrapes or eye irritation if a stray insect comes into contact with the face.

Emergency services have not reported a surge in serious incidents associated with the locusts, and local tourism offices emphasize that streets, promenades, and beaches remain open. For many visitors, the experience is characterized by hazier views and occasional dense pockets of insects rather than a blanket cover over the islands.

Impact on Flights, Beaches, and Outdoor Plans

As of now, commercial air traffic to and from Lanzarote, Tenerife, Gran Canaria, and Fuerteventura is operating on regular schedules. Aviation authorities are monitoring the situation, but the locust swarms have not reached the density or altitude that would typically interfere with aircraft operations. No widespread cancellations due to locusts have been reported.

On the ground, coastal resorts and urban centers are experiencing fewer insects than inland farming areas and arid landscapes. Travelers may notice clusters of locusts around streetlights at night or drifting across roads in the interior, while main beachfront promenades and hotel zones generally see more sporadic bursts as winds shift.

Outdoor activities such as hiking, cycling, and driving across desert interiors may feel less comfortable during peak swarm moments. Tour operators are advising guests to carry sunglasses, hats, and light long sleeves to shield against both the sun and the insects. Some off-road tours may adjust departure times to avoid periods of strongest winds carrying the locusts.

Beachgoers can expect normal sea conditions for the season. The locusts are airborne and tend to land mainly on vegetation and built surfaces rather than accumulating in significant numbers along the shoreline. Swimming, surfing, and sailing continue, although visibility for long-distance views may be slightly muted where calima dust remains in the atmosphere.

How Long the Swarm Could Last and What Experts Expect Next

Locust specialists and regional authorities describe this event as a transient episode, highly dependent on wind direction and strength. After their long journey from the Sahara, many of the locusts are already exhausted, and their survival window in the cooler, more humid Atlantic environment is limited without suitable breeding conditions.

A key concern for officials is whether any groups will successfully settle and reproduce on the islands. Currently, agricultural representatives indicate that the insects do not appear to be in optimal condition for establishing lasting populations. The temperatures, vegetation patterns, and land management practices in the Canaries differ significantly from typical breeding zones on the African mainland.

Weather forecasts suggest that the next few days will be critical in determining whether prevailing winds continue to push remaining swarms over the archipelago or disperse them out over the Atlantic. If winds shift, experts expect visible numbers around tourist areas to decline relatively quickly, even if some residual insects linger in inland valleys and fields.

Regional monitoring networks, including agricultural services and environmental agencies, are providing updates to local authorities. Any signs of locusts forming dense ground cover or damaging crops would trigger more robust control measures, but current observations indicate an event that is dramatic in appearance rather than devastating in impact.

Practical Advice for Travelers With Upcoming Trips

Travel and tourism officials are not advising visitors to cancel holidays to Lanzarote, Tenerife, Gran Canaria, or Fuerteventura at this stage. Instead, they recommend a flexible, informed approach: check recent local news coverage and weather bulletins in the days leading up to your departure, and be prepared for some temporary inconvenience if swarms remain in certain areas.

Travelers with respiratory conditions, strong insect allergies, or anxiety about insects may wish to choose accommodations in coastal zones, where breezes often help disperse flying insects more quickly than in sheltered interiors. Requesting sea-facing rooms on higher floors can further reduce the likelihood of locusts gathering on balconies and terraces.

Once on the islands, simple habits can enhance comfort during your stay. Keeping balcony doors closed during the windiest hours, shaking towels and clothing before use, and avoiding bright outdoor lights where insects congregate after dark can all limit close contact. Carrying basic eye drops and antihistamines, if recommended by a doctor, may help soothe any minor irritation.

For most visitors, the locust swarms are likely to register as an unusual weather-related footnote to their Canary Islands experience rather than a trip-defining crisis. With normal transport and core tourism services operating, and authorities continuing to monitor agricultural and public health implications, the destination remains open and welcoming while the skies slowly clear.
