What changes for holidaymakers in the south?

AEMET expects the strongest heat in the south and west of Gran Canaria and locally in the south of Lanzarote. According to the weather agency, more than 30C is possible in places, and high values were also expected in suitable spots on Tenerife.

For Las Palmas de Gran Canaria, AEMET forecasts up to 30C on Monday 26 October 2026. Santa Cruz de Tenerife reaches 27C and San Sebastián de La Gomera 28C.

According to AEMET, the calima is most noticeable above about 800 metres, in mid-altitude areas and on the peaks. On the southern slopes of the western islands it is stronger than on the north coasts.

Anyone planning a beach day does not necessarily need to change plans. The coastal towns remain comparatively mild: Arrecife 27C, Puerto del Rosario 26C, Santa Cruz de La Palma 26C.

Where the Saharan dust will be most visible

On Lanzarote and Fuerteventura, AEMET says the Saharan dust is mainly in higher layers of the atmosphere. At ground level the air there usually stays clearer than on the mountainous islands.

On Gran Canaria, Tenerife, La Gomera, La Palma and El Hierro, calima is more likely in mid-altitude areas and summit regions. The south-facing slopes are particularly affected.

Visibility can become significantly worse in these areas. AEMET gives no specific dust quantities and no official health warning for the period.

Travellers with respiratory conditions or sensitive eyes should still take care at higher altitudes. The sources do not mention any confirmed closure of paths or roads.

Wind and sea conditions: what to expect on coasts and peaks

According to AEMET, the wind is blowing from the north-east and can be strong at times in exposed spots. Some reports mention possible very strong gusts on the south-east and north-west coasts of the western islands.

At sea there is a north-easterly wind of force 5 to 6, occasionally freshening to force 7. AEMET also reports rough or very rough seas and waves of one to two metres from the north.

In mid-altitude areas and on the peaks, the wind turns south-easterly to southerly. There it can be strong at times in exposed spots during the morning.

This is not a calm day for boat trips and water sports. Anyone out on exposed coasts or at higher altitudes should keep an eye on how the wind develops.

How things continue on Monday and into Wednesday

For Monday 26 October 2026, AEMET continues to forecast calima. Added to that are cloudy skies, possible light occasional rain and largely stable temperatures.

According to AEMET, minimum temperatures remain almost unchanged. Maximum temperatures rise slightly, especially in the south and west and in mid-altitude areas.

The original report from Gomera Noticias speaks of a calima reaching all the Canary Islands until Wednesday. It remains open whether AEMET will issue an official warning level afterwards or whether the dust concentration will increase significantly.

The underlying report gives no precise dust pollution quantities for Sunday. Anyone wanting to be on the safe side should check the current AEMET forecast on the day of travel.

What holidaymakers can practically do now

Anyone heading to the south of Gran Canaria, Lanzarote or Tenerife should take plenty of water and avoid the midday heat. According to AEMET, temperatures there can rise above 30C.

For trips into the mountains, the rule is: the calima is most noticeable above about 800 metres. Anyone sensitive to dust is better off postponing hikes to a clearer day.

On the coasts, the north-easterly wind can be strong, with possible very strong gusts. Sun umbrellas and light objects should be secured.

The sources do not mention any closures, price changes, entry requirements or deadlines. This is a weather event, not an official restriction.

What remains unclear

AEMET has not published specific dust quantities for the period. The sources do not mention any official warning level for 25 or 26 October.

September 2026 was exceptionally warm in the Canaries: 24.4C on average, 2.6C above the 1991-2020 average. According to AEMET, that was the highest value since 1961.

Whether October turns out similarly cannot be deduced from the available data. The agency updates its warnings regularly.
