The Agencia Estatal de Meteorología (Aemet) forecasts rain and storms across the Canary Islands, with Saharan dust, known as calima, returning to the eastern islands and Tenerife. Visibility is expected to fall as the weather changes quickly.
Sunday, October 4, will bring a mix of conditions. Most of the region will start with sun or just a few clouds, while the northern slopes of the mountainous islands are likely to see more cloud cover. La Palma could get weak, patchy rain in the morning, and basic Tenerife may see isolated showers in the afternoon. Calima will be thickest in the east and at higher elevations; other areas will see less dust, but it will remain present. Light drizzle is possible in the northern mountainous areas, with isolated showers also possible in the central peaks and northeast of Tenerife. Calima will be more noticeable at altitude in the eastern islands.
Temperatures are holding steady or climbing. The southeast of Lanzarote and the interiors of Fuerteventura and Gran Canaria could reach 30 to 32°C, while some southern inland areas might hit 34°C. Northeast winds will blow along the coasts and may pick up in exposed areas. Higher ground will get breezes from the east and south.
Monday is not expected to bring much relief. Aemet forecasts clouds coming and going across the islands. The north may clear around midday, but clouds will build inland on the mountainous islands, bringing a chance of rain. Calima will persist, especially at higher elevations in the east. Temperatures will change little, with perhaps a slight rise. Winds will remain light to moderate from the northeast on the coast, with southern breezes inland and at higher elevations.
Tuesday looks less settled. Lanzarote and Fuerteventura will see high- and mid-level clouds, with a small chance of weak rain and isolated storms. The mountainous islands will have low clouds on their northern slopes and more clouds inland. Northern Tenerife and the peaks of Gran Canaria could see scattered showers and storms, while La Palma might get brief downpours. Calima will persist, especially at middle and upper elevations, and could reach low-lying parts of Lanzarote and Fuerteventura. Maximum temperatures will dip slightly in the eastern islands and central highlands. Moderate northeast winds will continue on the coast, with lighter, shifting breezes inland.
Each island faces its own mix. On Sunday, Lanzarote and Fuerteventura will be mostly clear, with calima at higher elevations. Temperatures could reach 30 to 32°C, or 34°C in the south. Gran Canaria's north will see clouds clearing by midday; the south and interior will heat up, and calima will affect middle and upper elevations. Tenerife's north has a slim chance of early rain before skies clear, but afternoon showers could hit the northeast and central peaks. La Gomera, La Palma and El Hierro can expect clouds and light calima, with moderate northeast winds. Southern lowlands could see highs near 30°C. Regional media have described La Palma as the basic focus of rainfall in this series of forecasts, with more persistent and locally intense precipitation reported at the start of October, while other islands experienced only weak, isolated showers.
Spain as a whole is on alert for severe weather. Aemet has issued red-level warnings for rain and storms in several regions. The pattern is unstable, and sudden weather changes are familiar in the Canary Islands, even when the islands are not at the center of the alerts. Other parts of Spain have faced heavy rain and disruption in recent days, and the season remains unpredictable.
Residents and visitors should stay alert: conditions can shift from sun and heat to rain and dust within hours, and calima and storms could disrupt daily life. Aemet's warnings and the unstable weather pattern make preparation impressive for anyone on the islands this week.
