Canary Islands weather shift 18 October with rain and wind

What changes for beachgoers on Sunday?

AEMET expects variable cloud and occasional light showers across the Canary Islands on 18 October 2026. A moderate north-easterly wind will blow along the coasts and may reach locally strong intervals.

For Las Canteras on Gran Canaria, AEMET reported moderate wind and rough seas on Sunday. The maximum temperature was 26 degrees and the water temperature 24 degrees. The maximum UV index was given as 7.

Conditions were calmer in Amadores, in the south-west of Gran Canaria: a maximum temperature of 25 degrees, a water temperature of 25 degrees, light wind and slight seas. Compared with Saturday, the expected maximum temperature there fell from 26 to 25 degrees.

AEMET issued no coastal warnings for the affected coastal areas. That does not rule out locally unpleasant conditions: seas can be rougher on exposed northern coasts. Anyone planning to swim or walk by the water should favour sheltered bays and keep away from rocks and breakwaters.

Which islands are most affected?

According to AEMET, Gran Canaria can expect a partly cloudy sky and occasional light showers. Cloud will increase in the north during the afternoon, where the sky may become overcast. In Las Palmas de Gran Canaria, 22 °C is expected at night and 26 °C during the day.

On Tenerife, the day begins partly cloudy with possible light showers. In the afternoon, cloud will become thick more often in the north, with locally persistent light rain possible. AEMET gives maximum temperatures of 26 degrees and minimum temperatures of 17 degrees for Santa Cruz de Tenerife.

La Palma, La Gomera and El Hierro show a similar pattern: in the afternoon, the northern slopes will become cloudy to overcast, and rainfall may be locally persistent. For Sunday, the figures given are 21–27 °C for Santa Cruz de Tenerife, 22–26 °C for Las Palmas de Gran Canaria, 22–27 °C for San Sebastián de La Gomera, 20–26 °C for Santa Cruz de La Palma, 18–23 °C for Valverde and around 21–26 °C for both Arrecife and Puerto del Rosario.

Lanzarote and Fuerteventura remain somewhat more stable. Both islands will have variable cloud and possible light showers, but no rainfall explicitly forecast as persistent.

What does this mean for walks and mountain hikes?

For the midlands and mountain areas of the mountainous islands, rain, poor visibility and strong gusts are the main factors. AEMET expects dense cloud and locally persistent light rainfall, especially on the northern slopes in the afternoon.

The wind will blow moderately from the north-east and may reach locally strong intervals on the south-eastern and north-western slopes of the mountainous islands. According to AEMET, this affects Gran Canaria, Tenerife, La Palma, La Gomera and El Hierro.

Anyone planning to hike on Sunday should allow for wet paths, poor visibility and wind gusts. In its regional forecast, AEMET advises checking routes in the northern midlands in particular. A rain jacket and sturdy footwear are sensible.

What are sea conditions like along the coasts?

For the coasts of Gran Canaria on Sunday, AEMET reported moderate wind and rough seas at Las Canteras. In Amadores, by contrast, seas were slight. The differences show that sheltered southern and south-western coasts are significantly calmer on Sunday than exposed northern and eastern coasts.

AEMET issued no coastal warnings for the affected areas. That does not mean every stretch of coast is without risk. On exposed northern coasts, seas can be rougher than the general forecast suggests.

What should residents and visitors actually do?

For beach plans on 18 October 2026, a sheltered bay in the south or south-west is advisable. The AEMET data show light wind and slight seas for Amadores, while Las Canteras in the north of Gran Canaria has moderate wind and rough seas.

For mountain plans, conditions are usually better in the morning than in the afternoon. AEMET expects the densest cloud and the most persistent rainfall in the afternoon on the northern slopes of the mountainous islands.

The AEMET coastal forecast for 18 October 2026 ran until 20:00 local time. An updated forecast may apply after that. Anyone out in the evening or at night should check the latest forecast.

Are there any warnings or restrictions?

For residents, expats and tourists, the available sources do not mention any new fees, access restrictions, closures, application deadlines or other regulatory changes. The weather forecast is a prediction and may be updated before Sunday.
