Quick Read
- A 1,300km-wide Saharan dust cloud is currently impacting the Canary Islands, triggering yellow weather alerts.
- AEMET reports that wind patterns are shifting, with clearing conditions expected to begin late Tuesday and persist through Wednesday.
- Health authorities advise residents and tourists to stay indoors, keep windows closed, and avoid strenuous exercise until air quality improves.
SANTA CRUZ DE TENERIFE (Azat TV) – A massive 1,300km-wide cloud of Saharan dust, known locally as calima, has blanketed the Canary Islands, forcing authorities to issue archipelago-wide yellow weather warnings as the region enters the peak of the Easter holiday travel period. The phenomenon, which began earlier this week, has significantly reduced air quality and visibility, complicating travel for thousands of tourists and residents alike.
The Timeline for Clearing Skies
According to the Spanish State Meteorological Agency (AEMET), the current atmospheric instability is acting as a catalyst for a transition in weather patterns. While the dust has caused widespread haze, the persistent easterly winds that trapped the particles are now beginning to shift. Meteorologists expect a progressive improvement in air quality starting late Tuesday, as westerly and northerly airflows arrive to act as a natural cleansing mechanism for the atmosphere.
Visibility is anticipated to improve significantly by Wednesday, particularly in the western province. However, AEMET cautions that higher altitudes and mountainous regions, as well as the easternmost islands of Fuerteventura and Lanzarote—which are geographically closer to the African coast—may experience lingering haze into Wednesday afternoon.
Public Health and Travel Safety
The intensity of this calima event has prompted urgent health advisories from local authorities. Residents and visitors are strongly encouraged to keep doors and windows closed to prevent fine dust infiltration. Health officials have specifically warned individuals with chronic respiratory conditions to avoid outdoor activities and to remain indoors whenever possible. For those who must travel, drivers are advised to reduce speeds and utilize headlights, as visibility has dropped to approximately 3,000 meters in some areas.
The arrival of the dust cloud coincides with a major influx of visitors for the Easter break, following a difficult week that saw the archipelago recover from intense rainfall and storms. While the current weather event is primarily a visibility and air quality concern, the government has maintained a state of pre-alert to ensure emergency services remain ready to assist those affected by the drop in air quality.
Impact on Holiday Operations
Despite the disruption, there is no expectation of a return to the severe storm conditions experienced earlier in the month. Temperatures, which hit unseasonably high peaks of 27°C earlier this week, are expected to stabilize as the dust clears. For the thousands of holidaymakers currently in the region, the shift in wind direction marks the beginning of a return to normal outdoor activities. AEMET notes that once the atmospheric pressure stabilizes, the risk of dust-related travel delays on roads and at regional transit points will subside significantly.
The severity of this event, coming immediately after a period of extreme rainfall, highlights the archipelago’s vulnerability to rapid shifts in atmospheric conditions; however, the predictable rotation of wind patterns confirms that this is a transient meteorological phenomenon rather than a long-term climatic shift.
