Massive waves batter the coastline during Storm Austen in Donostia, Spain

On October 23, 2026, in Donostia (San Sebastián), Spain, @meteogros shared footage showing powerful waves crashing against a concrete coastal seawall during Storm Austen. In the video, a massive wave strikes the wall, sending an enormous plume of white sea spray into the air. The wet promenade and low barriers in the foreground are exposed to the turbulent conditions, while dark waters churn beneath a thick blanket of gray storm clouds. According to reports, Storm Austen brought severe maritime conditions to the northern Spanish coast, prompting alerts as powerful waves battered the shoreline. The wave height at the Donostia offshore buoy reportedly reached 6.73 meters, while waves elsewhere along the Cantabrian coast and the Bay of Biscay reportedly reached between 7 and 10 meters.
