More news on this day
Unusual swarms of Saharan locusts have reached the eastern Canary Islands, dimming skies over Lanzarote, Tenerife, Gran Canaria and Fuerteventura and prompting questions from holidaymakers about what the outbreak means for planned trips.
What Is Happening in the Canary Islands Now
Over the past week, large swarms of locusts carried on strong Saharan winds have been reported across parts of Lanzarote, Fuerteventura, Gran Canaria and Tenerife. Local media and residents have shared images of hazy, insect-filled skies, particularly over rural and semi-desert areas, describing an unusual but visually dramatic phenomenon for the normally clear Atlantic archipelago.
Meteorologists say the insects originated in North Africa and were transported across the ocean by the same airflow that often brings calima, the region’s familiar Saharan dust haze. In this case, the dust-laden air has also acted as a highway for flying locusts, concentrating them over the easternmost islands where winds first make landfall.
Regional agricultural groups stress that the current wave resembles a migratory overflight rather than a full agricultural plague. Officials note that the insects have arrived in a weakened state after a long sea crossing and, for now, are not showing the dense ground coverage or crop destruction associated with major locust crises in mainland Africa.
Authorities on the islands remain on monitoring alert, but there have been no evacuations, no closures of major tourist zones and no changes to 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 is nuisance rather than danger. Locusts do not sting, do not carry venom and are not known as disease vectors in the way that mosquitoes can be. Visitors are more likely to experience discomfort from insects colliding with them outdoors or collecting on balconies, poolsides and windshields than any direct health threat.
Health specialists in the islands say that people with asthma, dust sensitivity or strong insect phobias may feel the effects more acutely, especially where locusts coincide with calima conditions that already reduce air quality. In such cases, simple precautions mirror those used during heavy dust episodes: limit prolonged outdoor exertion, keep hotel windows closed during the windiest periods and use masks or sunglasses if the air feels irritating.
There are currently no special vaccination, medication or quarantine requirements linked to the 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 insects, and local tourism offices emphasize that streets, promenades and beaches remain open. The experience for many visitors is one of hazier views and occasional dense pockets of insects rather than a blanket cover over the islands.
Impact on Flights, Beaches and Outdoor Plans
At the time of writing, commercial air traffic to and from Lanzarote, Tenerife, Gran Canaria and Fuerteventura is operating on regular schedules. Aviation authorities are tracking the situation, but the swarms have not approached the density or altitude that would typically interfere with aircraft operations, and no widespread cancellations due to locusts have been reported.
On the ground, coastal resorts and urban centers are seeing fewer insects than inland farming areas and arid open 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 experience more sporadic bursts as winds shift.
Outdoor excursions 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, both to shield from the sun and to make contact with insects less intrusive. Some off road tours may adjust departure times to avoid periods of strongest winds carrying the insects.
Beachgoers can expect normal sea conditions for the season. The locusts are airborne and 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 that is highly dependent on wind direction and strength. After undertaking a long crossing from the Sahara, many of the insects are already exhausted, and their survival window in the relatively cooler, more humid Atlantic environment is limited without suitable breeding conditions.
A key question for officials is whether any groups will successfully settle and reproduce on the islands. At present, agricultural representatives say the insects do not appear to be in optimal condition for establishing lasting populations, and temperatures, vegetation patterns and land management practices in the Canaries are different from typical breeding zones on the African mainland.
Weather forecasts suggest that the next couple of 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 sign that locusts are forming dense ground cover or damaging crops would trigger more robust control measures, but current observations point to 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 before 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 accommodation 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 make stays more comfortable. 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 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.
