Canary Islands Calima Pre-Alert: What Visitors Need to Know in Gran Canaria, Fuerteventura and Lanzarote

The Canary Islands Government has declared a calima pre-alert for Gran Canaria, Fuerteventura, Lanzarote and La Graciosa after elevated concentrations of African dust were recorded across the eastern islands. The measure took effect at 13:30 on Thursday, 3 September 2026, and officials warned that further dust could arrive, reducing visibility and aggravating respiratory or other chronic health conditions.

For visitors, the most important point is that a pre-alert is a call for awareness and preparation. It is not a travel ban, and the official declaration did not announce airport closures, cancelled ferries, closed resorts or a general restriction on beaches and attractions. Holidays can continue, but travellers in the affected islands should be ready to adjust outdoor plans, check live transport information and take particular care if they have asthma, chronic respiratory disease or a heart condition.

What has changed in the Canary Islands?

The regional Directorate General of Emergencies activated the pre-alert under the Canary Islands' emergency plan for adverse meteorological phenomena, known as PEFMA. The declared area comprises Gran Canaria, Fuerteventura, Lanzarote and La Graciosa. These are the islands closest to the current dust intrusion, with Fuerteventura, Lanzarote and La Graciosa singled out in the official notice as the places where elevated particle concentrations had been recorded most clearly. Dust had also reached Gran Canaria.

Authorities said additional convective development over Africa could send new supplies of airborne dust towards the archipelago. If that happens, particle levels may rise and visibility may deteriorate further. The Government is monitoring both the meteorological evolution and air-quality readings, and it has left open the possibility of changing the geographical scope of the pre-alert as conditions develop.

No official end time was included in the declaration. That matters for holiday planning: travellers should not assume that a forecast improvement, a clearer-looking morning or conditions on another island automatically mean that the pre-alert has ended. Equally, the absence of an end date does not mean severe conditions will persist indefinitely. Calima can vary substantially by island, altitude, wind direction and time of day.

What is calima and why does it affect a Canary Islands holiday?

Calima is the local name commonly used for airborne dust carried from North Africa. The Canary Islands' position off the African coast means that winds and atmospheric circulation can transport mineral particles from the Sahara over the Atlantic. The result may be a pale, milky or brownish sky, muted views and a dry or dusty sensation in the air.

The visual effect is only one part of the story. Fine particles can irritate the eyes, nose and throat, cause coughing and worsen symptoms in people with asthma, chronic bronchitis, cardiovascular disease or other existing conditions. Children, older people, pregnant travellers, smokers and people who work or exercise outside can also be more sensitive during a strong episode.

Visibility is another practical concern. Calima can soften or obscure long-distance views even when the sun is shining and there is no rain. For tourists, that may reduce the value of a volcano viewpoint, mountain panorama, photography tour or long coastal drive. When visibility becomes poor, it can also affect road safety and, in more serious cases, transport operations. The current pre-alert warns of the possibility of further visibility reduction, but it does not by itself establish that a particular flight, ferry or excursion has been cancelled.

This distinction is useful. A hazy sky over a resort does not automatically mean that every outdoor activity is unsafe, just as a normal-looking view from a hotel balcony does not prove that particle levels are low. Travellers should combine what they can see with official air-quality and emergency information, their own health needs and the advice of operators responsible for individual activities.

Fuerteventura: take extra care with exposed outdoor plans

Fuerteventura is one of the islands where the Government reported elevated particle concentrations, and its open terrain makes many popular holiday activities highly exposed. Beach days in Corralejo, Caleta de Fuste, Costa Calma or Morro Jable may still be possible, but a strong calima episode changes the comfort calculation. Long periods in the open air, beach running, cycling, dune walks and strenuous watersports preparation can mean sustained exposure to dusty air.

Visitors planning to cross the island by hire car should check visibility before departure and leave more room than usual between vehicles if the horizon becomes obscured. Headlights may help other road users see the car in reduced visibility, but they are not a licence to maintain normal speed. Dust can also settle on windscreens, lights and camera lenses, so clean them carefully rather than wiping dry grit across glass or optical surfaces.

The Corralejo dunes and the long landscapes of the Jandia peninsula are celebrated precisely because they feel expansive. On a dusty day, those views may be subdued. Moving a panoramic road trip or a long hike to a clearer day can produce a better experience as well as reducing exposure. Indoor cultural visits, a shorter meal-led itinerary or a relaxed hotel day can be a sensible temporary alternative.

Lanzarote: volcanic landscapes may lose visibility

Lanzarote was also highlighted among the islands with elevated dust levels. The island's tourism appeal depends heavily on open volcanic scenery, including viewpoints, vineyards, coastal lookouts and the landscapes around Timanfaya. Calima can reduce the contrast that normally defines those places. Visitors may find that distant cones, coastlines or neighbouring islands are difficult to see even when local conditions remain dry.

That does not amount to a general closure of Lanzarote's attractions. Travellers with reservations should check directly with the attraction, tour provider or transfer operator rather than cancelling on assumption. Operators can respond to local conditions, and visibility may differ between Playa Blanca, Puerto del Carmen, Costa Teguise, Arrecife and the island's higher or more exposed areas.

Active itineraries deserve more caution. A long cycle ride, trail run or exposed walk involves deeper and faster breathing, increasing the amount of air drawn into the lungs. During poor air quality, reducing intensity or switching to an indoor activity is particularly relevant for anyone who is sensitive to dust. Travellers using inhalers or other prescribed medicine should keep them accessible and continue following their clinician's instructions.

Drivers should also remember that Lanzarote's roads often encourage long sightlines across open land. When those sightlines shrink, overtaking and judging distances become more difficult. Slow down, avoid abrupt manoeuvres and allow extra time for airport, ferry and restaurant bookings.

La Graciosa: check both weather and ferry information

La Graciosa is included explicitly in the pre-alert and was grouped with Lanzarote and Fuerteventura in the official account of elevated particle concentrations. For day-trippers, the island requires an additional planning step because most visits involve the ferry between Orzola and Caleta de Sebo.

The declaration did not announce a suspension of that service. Nevertheless, visitors should confirm their sailing before travelling to Orzola, especially if visibility or other weather conditions worsen. Ferry operators and port authorities provide the relevant operational information; a regional calima pre-alert should not be treated as a substitute for a live departure check.

Once on La Graciosa, shade is limited on many routes and journeys are often made on foot, by bicycle or in authorised vehicles. A long cycle loop that feels manageable in clear air may be less comfortable when dust concentrations are high. Carry water, reduce exertion, protect the eyes from irritation and retain enough flexibility to shorten the route. Visitors should also avoid treating reduced visibility as an invitation to leave marked or familiar routes.

Gran Canaria: conditions can vary sharply around the island

Dust had also reached Gran Canaria when the pre-alert was declared. The island's size, elevation and varied terrain mean visitors may encounter very different conditions between Las Palmas de Gran Canaria, the southern resorts, inland villages and high viewpoints.

A clear patch at sea level does not guarantee good visibility around the summit area, while a hazy urban horizon does not establish the status of every beach. Check the specific municipality and route, particularly before driving towards Tejeda, Roque Nublo, Pico de las Nieves or other elevated destinations where the journey and the view are central to the excursion.

In the south, visitors staying around Maspalomas, Playa del Ingles, Meloneras, Puerto Rico or Mogan should approach the day pragmatically. A gentle beach or pool schedule may require less exertion than an inland hike, but sensitive travellers can still experience irritation outdoors. If the air looks dusty or symptoms appear, move inside, close windows where appropriate and use air conditioning in recirculation mode if the system allows it.

Las Palmas de Gran Canaria offers useful indoor alternatives, from museums and galleries to restaurants and shopping, although opening hours and admission arrangements should always be checked. Rebalancing one day of an itinerary is often more effective than forcing a viewpoint-heavy route when the views are obscured.

Are flights to the Canary Islands affected?

At the time covered by the official declaration, no general airport closure or blanket flight cancellation was announced as part of the calima pre-alert. Gran Canaria Airport, Fuerteventura Airport and Lanzarote Airport remain critical gateways for the affected islands, while La Graciosa is normally reached by sea from Lanzarote.

That confirmed position should not be turned into a promise that every individual service will operate exactly on time. Airlines, airports and air-traffic authorities make operational decisions using live conditions, and visibility can change. Anyone flying should check the airline's app or website and the airport departure board before leaving their accommodation. Travellers should rely on a message tied to their flight number, not on an old social-media image from a previous calima episode.

Allowing extra time is sensible when driving visibility is reduced, but passengers should not arrive excessively early unless their airline or airport advises it. Standard airport procedures still apply. Keep contact details up to date, monitor notifications and preserve receipts if a genuine disruption leads to additional costs that may be relevant to an airline, tour operator or insurer claim.

The same principle applies to inter-island connections. A through itinerary involving a flight, ferry and hire car has less tolerance for delay than a simple resort stay. Check each segment separately and avoid assuming that a disruption to one island or operator automatically affects the entire Canary Islands network.

Practical health advice during calima

Canary Islands public-health guidance for calima episodes centres on reducing exposure. People who are sensitive to airborne particles are advised to avoid prolonged time outside, limit physical effort in the open air, keep windows closed and stay well hydrated. Dust on indoor surfaces is best removed with a damp cloth, which traps particles instead of sending them back into the air.

For hotel and holiday-rental guests, that can translate into a few simple choices: close balcony doors when outdoor air is visibly dusty, avoid leaving bedding or towels outside, and ask reception or the property manager how the ventilation or air-conditioning system should be used. Do not block vents or modify equipment without permission.

Contact lenses may become uncomfortable when eyes are irritated. Travellers who normally switch between lenses and glasses may prefer glasses during the dustiest periods, following their usual eye-care advice. Saline products, masks or air purifiers may help some people, but anyone with a diagnosed condition should prioritise guidance from a medical professional who understands their circumstances.

Seek medical assistance if symptoms are severe, unusual or worsening. Spain's emergency number is 112. It should be used for emergencies, not routine travel or weather questions. Pharmacies, hotel staff, tour representatives and travel insurers can help visitors identify appropriate non-emergency services.

Should visitors cancel beach, hiking or sightseeing plans?

A blanket cancellation is not justified by the pre-alert alone. The better response is to match the activity to current local air quality, visibility and personal vulnerability.

Beach visitors can shorten exposure, choose a less strenuous day and take indoor breaks. Swimmers should continue to follow normal flag and lifeguard instructions; calima does not replace coastal safety rules. A dusty sky is not evidence that sea conditions are safe, and clear air is not evidence that currents are harmless.

Hikers, runners and cyclists should be more conservative because sustained exercise increases breathing rate. Rescheduling a demanding route, reducing distance or choosing an indoor session may be the right decision, particularly on Fuerteventura, Lanzarote and La Graciosa where elevated particles were specifically reported. If an organised excursion goes ahead, guests should still tell the guide about relevant health concerns and carry prescribed medication.

For sightseeing, ask whether the destination depends on a distant panorama. A museum, market, historic quarter, winery visit or long lunch may retain most of its value during haze. A summit viewpoint or landscape photography trip may not. This is less about abandoning the holiday than using flexibility to protect both health and the quality of the experience.

Advice for hotels, holiday rentals and tour operators

Tourism businesses can reduce confusion by giving guests short, specific updates. The useful message is not simply that there is "bad weather." Guests need to know which islands are covered, that the issue is airborne African dust, that the alert status may change and that they should verify individual transport or activity arrangements.

Accommodation teams should make indoor alternatives easy to identify, explain how room ventilation works and pay attention to guests who disclose asthma or other chronic conditions. Excursion companies should assess visibility and exertion on the actual route rather than applying assumptions from another part of the island. Car-hire providers can remind customers to clean windscreens safely and use greater caution when visibility falls.

Clear language also protects destination confidence. There is a meaningful difference between an official pre-alert, an air-quality reading, an AEMET weather warning and an operator cancellation. Combining them into a vague claim that the Canary Islands are "closed" would be inaccurate. Minimising the episode would be equally unhelpful for visitors whose health makes dust exposure significant.

How travellers should follow the episode

The official territorial scope can be revised, so visitors should check Canary Islands Government emergency updates and current air-quality information. AEMET forecasts provide the wider meteorological picture, while airlines, airports, ferry companies, attraction managers and municipalities remain the authoritative source for individual services or access arrangements.

When reading updates, note both the publication time and the island named. Conditions reported in Fuerteventura on Thursday afternoon may not describe Gran Canaria on Friday morning. Screenshots circulate long after circumstances have changed, and past calima videos are often reposted during new episodes. Use dated, official information wherever possible.

The pre-alert's open-ended monitoring approach is appropriate because dust transport is dynamic. Further African dust may arrive, the affected area may expand or contract, and visibility can improve at different rates. Visitors with flexible itineraries have an advantage: keep confirmed bookings under review, move strenuous outdoor plans when conditions justify it and use the islands' indoor cultural and food experiences when the landscape is obscured.

The bottom line for Canary Islands holidays

The September calima is a real travel-planning issue, especially in Fuerteventura, Lanzarote and La Graciosa, where elevated particle concentrations were already recorded, and in Gran Canaria, where dust had also arrived. The official concern is twofold: particle exposure may aggravate chronic or respiratory illness, and further dust could reduce visibility.

It is not, on the information announced with the pre-alert, a reason to assume that flights, ferries, resorts, beaches or attractions across the eastern Canary Islands have stopped operating. Most travellers can continue their holidays with sensible adjustments: reduce strenuous outdoor activity, protect vulnerable companions, drive cautiously, check live transport details and follow official updates.

The best response is measured rather than dramatic. Calima is part of the Canary Islands' weather reality, but every episode develops differently. Treat the current declaration seriously, distinguish regional caution from a specific closure, and let verified local conditions guide each day's plans.
