Warning for Intense Calima Issued Across the Canary Islands
A widespread calima alert has been activated across the Canary Islands, with experts warning that this episode could be stronger and more noticeable than usual.
The Canary Islands Government has issued a pre-alert from midday on Monday (30th March), based on forecasts from AEMET, as a dense plume of Saharan dust moves towards the islands.
Why This Calima Is Expected to Be More Intense
This isn’t a typical light dust haze. Forecasters say several factors are combining to make this event more significant:
- Large volume of dust: A strong flow of air from the Sahara is carrying a higher concentration of fine particles than usual
- Widespread coverage: The dust cloud is expected to affect all islands, not just the eastern ones
- Higher altitude impact: Unlike some calima events, this one will also heavily affect mid-level and mountain areas
- Longer duration: Conditions are expected to build on Monday and peak throughout Tuesday
These elements mean the calima will be thicker, more persistent, and more noticeable across the entire archipelago, and could turn the skies orange.
What to Expect Over the Next 48 Hours
Conditions will change quickly from midday on Monday, as the dust moves in from east to west.
Lanzarote and Fuerteventura will be affected first, before the haze spreads to Gran Canaria, Tenerife, and then the western islands, later in the day.
By Tuesday, skies are expected to be heavily overcast with dust, giving them an orange tint and reducing visibility across the islands. Temperatures may also rise slightly due to the dry, warm air.

Health and Visibility Concerns
This type of calima can have a noticeable impact on air quality.
Fine dust particles (PM10) can irritate the airways, particularly for people with asthma, allergies or other breathing conditions. Even healthy individuals may notice dry throats, itchy eyes or reduced visibility outdoors.
Officials are urging people to take simple precautions:
- Keep windows and doors closed
- Avoid outdoor exercise during peak hours
- Wear a face covering if you have respiratory issues
- Drive carefully, as visibility may drop significantly
Take It Seriously
While calima is common in the Canary Islands, the intensity expected this time, combined with its wide reach and duration, means it could have a greater impact than usual.
Authorities are advising everyone to stay informed and follow safety guidance until conditions improve.
