The error associated with three datasets of significant wave height is estimated using the triple collocation method. The method requires three independent data sources, so data from a spectral wave model (SWAN), satellite altimeter and wave buoy are used. The three datasets are located in the Canary Islands area, in the North Atlantic Ocean, and include a 10 years period of data. The triple collocation results show differences when using a different referential, and the causes of those differences are discussed in the paper. The lowest error was obtained when using the satellite as referential (0.16 and 0.26 m for the wave buoy and SWAN model, respectively). The error results from the triple collocation method for satellite and SWAN are also compared to the ones obtained using the least square error method with the wave buoy as the true value. The results from the two methods show a difference of 0.08 and 0.16 for the satellite and SWAN, respectively.
