A sharp and potentially hazardous change in weather conditions is set to affect the Canary Islands from Thursday, 9 April, as an Atlantic фронt linked to a polar air mass approaches the archipelago. According to the Agencia Estatal de Meteorología (AEMET) and the Canary Islands Government’s Directorate-General for Emergencies, a series of alerts have been activated in response to what is expected to be one of the most significant weather events in recent weeks.
The arrival of this cold air mass will displace the warmer, more stable conditions that have prevailed in recent days, replacing them with a markedly more unstable and dynamic weather pattern. Authorities have placed the entire archipelago under close monitoring, with particular concern focused on coastal areas and high-altitude zones, where the most severe impacts are anticipated.
Coastal conditions: highest alert at sea
The most critical situation is expected along the coasts. The regional government has escalated the maritime alert level across all islands, with an orange warning in force for Lanzarote due to particularly dangerous sea conditions.
In this area, a powerful north-westerly swell is forecast to generate waves that could reach up to six metres in height. Across the rest of the archipelago, a yellow warning remains active, with wave heights between four and five metres expected, creating hazardous conditions for any maritime activity.
These conditions will be especially dangerous during high tide periods, when the force and reach of the waves increase significantly. Despite relatively low tidal coefficients, the energy of the Atlantic swell poses a real threat to swimmers, small vessels and anyone near exposed coastal infrastructure.
Intensifying winds: gusts of up to 80 km/h
Alongside the deteriorating sea state, strong winds will become a defining feature of the weather event. A north-westerly flow will dominate, blowing with moderate to strong intensity across the islands.
Wind gusts are expected to exceed 70 km/h in many areas, with peaks of up to 80 km/h possible in more exposed locations, particularly during Thursday afternoon. The most affected zones include:
- Tenerife: high-altitude areas, ridge lines and the far west
- Gran Canaria: south-eastern midlands and western and north-eastern slopes
- La Palma: mountain peaks and both eastern and western slopes
- Lanzarote and Fuerteventura: inland and open terrain
In these areas, the strength of the wind may lead to localised disruption, especially in exposed and elevated terrain.
Rain, falling temperatures and possible snow on Teide
The advancing front will also bring widespread cloud cover and increased atmospheric instability. On the higher islands, particularly in northern areas, skies will remain overcast with light to moderate rainfall, which may become persistent at times throughout the day.
Even the eastern islands, typically less affected by such systems, are expected to see rainfall, especially during the morning hours.
Temperatures will drop noticeably across the archipelago. While coastal areas may still register between 20°C and 21°C, the combination of wind and humidity will significantly lower the perceived temperature, creating a much colder sensation.
In higher areas of Tenerife, particularly around Mount Teide, conditions will be markedly colder. AEMET maintains the probability of light frost, and with the arrival of polar air, the first snowfall or sleet of the episode cannot be ruled out.
Outlook: gradual stabilisation, but cooler conditions persist
This episode forms part of a broader weather system affecting not only the Canary Islands but also mainland Spain. The most intense phase is expected between Thursday and Friday, after which conditions should begin to stabilise gradually from Saturday, 11 April, as high pressure systems regain influence.
However, the drop in temperatures is expected to persist, leading to a noticeably cooler weekend than is typical for this time of year.
Authorities urge caution
Given the combination of strong winds, rough seas and unstable weather, the Canary Islands Government has issued a series of recommendations. Residents and visitors are advised to:
- Avoid unnecessary travel in mountainous areas
- Secure loose objects such as awnings or outdoor furniture
- Stay away from breakwaters, piers and exposed coastal zones
The authorities emphasise that the force of the sea and wind during this episode could pose serious risks, particularly in the most exposed areas of the archipelago.
