Weather Warning in the Canary Islands: Understanding the Calima Episode

A weather warning has recently been issued for one of Europe’s most beloved holiday destinations, the Canary Islands, as a significant calima episode unfolds. This natural phenomenon, characterized by the transport of Saharan sand and dust across the Atlantic Ocean, is causing concern among residents and tourists alike.

What is Calima?

Calima refers to a weather event where strong winds carry fine particles of sand and dust from the Sahara Desert to the Canary Islands. The state meteorological agency, AEMET, has issued a warning indicating that this calima episode will persist until Wednesday. During this time, the islands will experience hazy skies, reduced visibility, and hot, dry conditions.

Effects on Visibility and Air Quality

As the calima settles over the islands, it creates a thick haze that significantly reduces visibility. The skies take on an orange tint due to the dust, making for a surreal yet concerning atmosphere. The air quality deteriorates as the dust settles, leading to potential health risks. Individuals with respiratory issues, such as asthma, may find their symptoms exacerbated, while others might experience eye irritation and headaches.

Areas Affected

The calima first impacted Lanzarote and Fuerteventura on Monday, with the haze quickly spreading to Gran Canaria, Tenerife, and the western islands. Residents and visitors are now facing heavily overcast skies, which can be both unsettling and hazardous.

Safety Precautions

Officials are urging those in the Canary Islands to take necessary precautions during this weather event. Recommendations include:

• Keeping windows and doors closed to prevent dust from entering homes.
• Avoiding outdoor exercise, especially during peak hours when the dust concentration is highest.
• Wearing face coverings if respiratory issues are present.
• Driving carefully, as reduced visibility can pose risks on the roads.

The Unique Nature of Calima

While calimas are not uncommon in the Canary Islands, the intensity and duration of this particular episode are noteworthy. In the past, severe calimas have led to the closure of airports, as planes are unable to conduct visual approaches due to the thick dust. Interestingly, these weather events often follow clear skies and can be followed by rain, particularly in the winter months.

Temperature and Health Considerations

During calima episodes, temperatures can soar, sometimes reaching as high as 45°C (113°F), with nighttime temperatures remaining uncomfortably warm. Residents are advised to stay hydrated and seek medical attention if they feel unwell, as the combination of heat and poor air quality can lead to health complications.

The Arrival of Foreign Insects

In addition to the dust, calimas can also bring unexpected visitors. In recent events, foreign insects such as locusts, ladybirds, and dragonflies have been swept up in the winds and found their way to Lanzarote. This phenomenon adds an unusual twist to the already complex nature of calima episodes.

Duration of the Event

Typically, calimas last anywhere from half a day to three days. This current episode is expected to conclude late on Wednesday, but the impact on daily life and health can linger even after the dust settles.

As the Canary Islands navigate this calima episode, residents and tourists alike are reminded to stay informed and take precautions to ensure their safety and well-being during this challenging weather event.
