By Wednesday, a very strong Calima carrying Saharan dust will spread across Tenerife and La Gomera. This forecast is based on the Copernicus CAMS model and measurements from the European Environment Agency.
On Tenerife, the daily average level of particulate matter is expected to be 142 micrograms of PM10 per cubic metre on Tuesday, meaning air quality will be very poor. According to the data, air quality on La Gomera is also very poor, at 136 micrograms of PM10.
A severe Calima is set to begin as early as Monday on El Hierro and Gran Canaria. The forecast predicts 97 micrograms of PM10 for El Hierro and 75 micrograms for Gran Canaria. On both islands, the situation is set to worsen by Wednesday, resulting in a very severe Calima.
Canary Islands: Calima to affect all the islands by Wednesday
On Wednesday, PM10 levels will rise to 133 micrograms per cubic metre in Gran Canaria and to 118 micrograms in El Hierro. This means that air quality on both islands is very poor. La Palma, meanwhile, will be affected by severe Calima from Monday to Wednesday, with PM10 levels reaching 97 micrograms there on Tuesday.
Fuerteventura and Lanzarote are set to experience strong Calima winds on Tuesday. Levels of 78 micrograms of PM10 are forecast for Fuerteventura and 86 micrograms for Lanzarote on Tuesday. A day later, pollution levels on both islands are set to rise further, with forecasts indicating 113 and 108 micrograms of PM10 respectively.
Fine Saharan dust can irritate the eyes and airways. People with asthma, respiratory or heart conditions, as well as the elderly and pregnant women, should avoid physical exertion outdoors. They are also advised to keep windows and doors closed and to drink plenty of fluids.
