The oceanographic buoy of the University of Oviedo, located 4 km north-west of the port of Cudillero, registered a wave of 20.87 meters of height last Sunday, February 2, between 12 AM to 1 AM.

During this period of time, the significative height of the wave (a parameter that gives an approximate idea of the height of the wave) reached 10.54 me. Despite its proximity to the coast, where waves tend to lose height, the wave was only 6 meters shorter than the great wave of 26.13 m registered by th Augusto González de Linares buoy of the Spanish Institute of Oceanography 40 km north of Santander on January 24, 2009, and falls 21 cm short of the height required to be classified as a "giant wave".

El viento más intenso en esta franja de la costa en lo que va de temporal se produjo el 4 de febrero entre las 16 y las 17 horas, con una velocidad media de 63 km/h y ráfagas de 85 km/h a nivel del mar. En ese momento la altura significativa de la ola era de 2.72 metros alcanzándose una altura máxima de 4.35 metros. La boya oceanográfica instalada en la costa de Cudillero es un equipamiento universitario del Campus de Excelencia Internacional. Este instrumento dispone de un conjunto de sensores meteorológicos y oceanográficos que proporcionan información a tiempo real sobre los nutrientes, el plancton y las corrientes marinas. The most intense wind in this area of the coast during this rough weather took place on February 4, between 4 PM and 5 PM, reaching a speed of 63 km/h, with bursts of up to 85 km/h at sea level. At the time, the significative height of the wave was of 2.72 m, reaching a maximum height of 4.35 m. The oceanographic buoy installed on the coast of Cudillero is a university equipment of the Campus of International Excellence. This instrument has a set of meteorological and oceanographic sensors that provide real-time information on nutrients, plankton and marine currents.
