Calima: Poor air quality affects four Canary Islands
The Calima forecast, based on the Copernicus CAMS model and measurements from the European Environment Agency, indicates strong Calima on Gran Canaria and Fuerteventura on Thursday. The daily average PM10 level is 58 micrograms per cubic metre on Gran Canaria and 52 micrograms on Fuerteventura. Air quality is poor on both islands.
On Friday, the severe Calima will move towards Tenerife and La Gomera. The forecast predicts a daily average PM10 concentration of 63 micrograms per cubic metre for Tenerife and 58 micrograms for La Gomera. Air quality will be poor there too.
Rain and thunderstorms in the higher elevations of La Palma and Gran Canaria can cause large volumes of water to flow down the barrancos to the coast. Particular caution is therefore advised in and around these ravines. The fine dust can irritate the eyes and respiratory tract on La Gomera, Tenerife, Gran Canaria and Fuerteventura. People with respiratory or heart conditions, the elderly and pregnant women should avoid physical exertion outdoors and keep windows and doors closed.
