The General Directorate of Emergencies of the Canary Islands Government has declared a pre-alert due to the upcoming spring tides, which are set to occur between Wednesday, 18 September, and Friday, 20 September. These tides are expected to be among the largest of the year, driven by the combination of a full moon and equinoctial, or Pine Tides.
During this period, the sea level will rise significantly, causing beaches and coastal bathing areas to submerge. In some cases, waves may even reach promenades and streets close to the shore, particularly in areas facing south. The most critical times for high tides are:
- Tuesday, 17 September: between 13:20 and 13:45
- Wednesday, 18 September: between 1:45 and 2:15 am, and between 13:55 and 14:25 pm
- Thursday, 19 September: between 2:25 and 2:55 am, and between 14:40 and 15:10 pm
- Friday, 20 September: between 3:05 and 3:35 am, and between 15:20 and 15:50 pm
This phenomenon, intensified by the ‘supermoon,’ increases the strength and height of the tides. Residents and visitors along the Canary coasts are urged to exercise caution, particularly during high tide periods, and to avoid dangerous areas near the shore.
In response, the Special Civil Protection and Emergency Plan for Flood Risk (Peinca) has been activated to mitigate potential flooding and coordinate emergency actions if necessary. The Canary Islands Government advises the public to stay informed and follow any safety instructions provided by authorities during this period.
