The monitoring network of the Hydrographic Institute of the Portuguese Navy recorded waves of 13 meters, off Leixões, Matosinhos, and 14 meters, in Nazaré, during the passage of the storm Dora through Portugal.
The bad weather in the wake of the storm Dora was felt most intensely during the afternoon of the 4th and the dawn of the 5th of December. According to the Navy, “this storm, caused by the spread of low pressure in the North Atlantic, generated waves of strong intensity”.
The highest was registered by the Nazaré Costeira buoy, with “a maximum height of 14 meters”, at 5 pm on Friday, says the Navy. The same device reported, at 8 pm, a wave with a significant height of 8.9 meters. This value is obtained by calculating the average height of one third of the largest waves over a given period of time.
