A wave of 9.9 metres was recorded off the coast of Faro on Sunday (October 22), the day that the Algarve was hit by Storm Bernard.
The unusually high wave was detected by one of the buoys of the Hydrographic Institute, a Navy laboratory dedicated to marine sciences and technologies.
There are buoys located in Faro, Sines, Nazaré, and Leixões, which between October 17 and 23 registered waves of over 15 meters.
The highest wave was recorded in the north of Portugal by the Leixões buoy, with a height of 15.8 meters on the morning of Friday, October 20. The second highest wave, at 11.7 meters, was recorded on the same morning in Nazaré.
As the Resident reported earlier this week, over 400 bad weather-related incidents were reported across Portugal on Sunday due to Storm Bernard, with over 300 being reported in the Algarve. Most of the incidents were related to tree falls, flooding, road cleaning, and also structural collapses.
