The State Meteorological Agency (Aemet) has officially activated a yellow weather warning in the Canary Islands for this Monday, citing hazardous coastal conditions caused by strong waves and intensifying trade winds. The alert affects five islands and comes as an unstable air mass moves over the archipelago, reinforcing maritime instability across exposed coastal areas.
Five Islands Under Coastal Risk
According to Aemet’s latest bulletin, the warning applies to:
- Tenerife
- Gran Canaria
- La Palma
- La Gomera
- El Hierro
The main concern is the combination of northeasterly trade winds and swell, which is expected to generate rough sea conditions, particularly along coastlines directly exposed to the wind flow. Authorities are urging residents and visitors to exercise extreme caution near beaches, breakwaters, piers and coastal promenades.
The phenomenon is described as combined sea and strong wind intervals, with conditions that may pose risks to swimmers and anyone approaching wave-exposed areas.
Coastal Slopes Most Exposed
The impact will be most noticeable on the slopes facing the trade winds, where gusts will intensify maritime turbulence. While mainland Spain is currently focused on the development of an Atlantic trough that could evolve into a new DANA system, the Canary Islands’ primary risk lies offshore, with the sea and wind becoming the dominant weather factors.
Beach users are advised to:
- Respect red flag warnings
- Avoid entering the water where conditions are unstable
- Stay clear of wave-breaking zones and exposed harbour areas
Cloud Cover and Wind Intensification
Beyond the coastal alert, Monday’s forecast includes cloudy skies in the northern parts of the higher islands, where light rainfall may occur, especially during the morning hours. Elsewhere, skies will remain partly cloudy, with intervals of high cloud cover.
The trade winds will continue to strengthen throughout the day. Aemet forecasts strong wind intervals with very strong gusts possible in mountainous areas and on north-western and south-eastern slopes of the higher islands. These intensified winds are the key driver behind the deteriorating sea state.
Temperatures Remain Mild
Despite the maritime instability, temperatures across the Canary Islands are expected to remain largely stable. Both minimum and maximum values will show little variation, in contrast to mainland Spain, where significantly colder conditions — including snowfall in central regions — are forecast.
Along the Canary coasts, the weather will remain relatively mild, although wind chill could be noticeable in elevated areas due to persistent gusts.
The yellow warning for coastal phenomena will remain in effect as long as Atlantic pressure systems continue to reinforce the strong northerly flow affecting the islands. Authorities continue to monitor the situation and recommend following official updates throughout the day.
