Canary Islands Braces for Calima: A Deep Dive into the Dust and Rising Temperatures
The Canary Islands are preparing for a shift in weather conditions this Monday, February 16th, with the arrival of a significant calima event. Skies are expected to remain clear across the archipelago, though some high-level cloud cover is anticipated in the western provinces later in the day. The primary concern is the reduced visibility caused by dust in suspension, particularly impacting specific areas.
What is a Calima?
A calima is a meteorological phenomenon originating in the Sahara Desert. Strong winds carry dust and sand particles across the Mediterranean Sea and towards the Canary Islands, resulting in hazy skies, reduced visibility, and a noticeable layer of dust on surfaces. These events can impact air quality and pose health risks, especially for individuals with respiratory conditions.
Island-by-Island Breakdown: Where Will Be Most Affected?
While the calima will be widespread, certain islands and areas will experience more significant impacts:
- Gran Canaria: Expect particularly reduced visibility on the east, south, and west sides of the island.
- Tenerife: The east, south, and west will be most affected, especially during the afternoon.
- Lanzarote & Fuerteventura: Intense calima conditions are expected at lower levels throughout much of the day.
- La Palma: The eastern side of the island will see the greatest impact.
- La Gomera & El Hierro: General impact across both islands, with the south being more affected.
Dust concentrations are estimated to range between 50 and 200 micrograms per cubic meter at ground level, with denser layers above 400-500 meters.
Rising Temperatures: A Taste of Summer
Alongside the calima, temperatures are set to rise significantly, increasing by 3°C to 8°C compared to the previous day. This warming trend will be most pronounced in inland areas, creating conditions that feel more akin to summer than mid-February.
Wind and Sea Conditions
Winds will be generally light to moderate from the east, shifting to the southeast in higher elevations. Sea conditions are expected to improve, with waves decreasing from rough to strong swell, reaching heights of 3 to 2 meters in open northern waters and the west coasts of Fuerteventura, and Lanzarote.
Health Considerations and Safety Advice
The calima can exacerbate respiratory problems and cause discomfort. Authorities recommend following safety guidelines, including staying indoors when possible, keeping windows closed, and drinking plenty of fluids. Individuals with chronic illnesses should capture extra precautions.
Pre-Alert Status and Ongoing Monitoring
The Canary Islands Government has declared a pre-alert status for calima across all islands, effective from 06:00 hours on Monday, February 16th. This decision is based on information from the State Meteorological Agency (AEMET) and other available sources. A pre-alert for coastal phenomena and wind is also in effect.
Frequently Asked Questions (FAQ)
What is the visibility expected to be during the calima?
Visibility will be reduced, particularly in the areas mentioned above. It could be reduced to around 3,000 meters in some locations.
Are there any specific health risks associated with the calima?
The calima can aggravate respiratory conditions and cause eye and throat irritation. Individuals with pre-existing health issues should take extra precautions.
How long is the calima expected to last?
Avisos de la AEMET indicate the calima is expected to last for two days, Monday 16 and Tuesday 17.
