Yellow Weather Warning activated for dangerous seas in the Canary Islands
AEMET has issued a yellow weather warning for coastal conditions in parts of the Canary Islands, while the regional government maintains a pre-alert for strong waves across the archipelago. The warning will affect Tenerife and Gran Canaria on Monday, 9th March, from 12:00pm until 11:59pm, due to deteriorating sea conditions.
According to AEMET, the alert specifically applies to the east, south and west coasts of both islands, where north-easterly winds of 50 to 61 km/h (force 7) are expected, particularly in the south-east of Tenerife and the west of Gran Canaria.
Pre-alert for strong waves across the islands
The Canary Islands Government confirmed on Friday that the situation has been downgraded to a pre-alert for rough seas across all islands.
The decision was taken based on forecasts from AEMET and other available data, under the Canary Islands’ Specific Emergency Plan for Adverse Meteorological Phenomena (PEFMA).
Authorities warn that combined northern swell could reach heights of 3 to 4 metres, with north or north-easterly winds of force 4 to 5 (20–38 km/h) strengthening to force 7 (50–61 km/h) in exposed areas.
Sea conditions are expected to worsen, with moderate seas increasing to rough or very rough, driven by strong wind waves. Swell periods are forecast to range between 10 and 13 seconds.
Northern coasts most exposed
The north-facing coasts of the islands and the channels between islands are expected to be the most affected by the swell. In contrast, south-west facing coasts are likely to experience calmer conditions.
High tide levels will also contribute to the situation, with tidal coefficients remaining relatively high.
Authorities are urging residents and visitors to exercise caution along coastal areas and to follow the safety advice issued by the Directorate General for Emergencies, particularly in exposed coastal zones.
