An analysis skewness bias (SB) was made of the altimetry determination of the level of the Sea of ​​Azov, caused by the deviation of the distribution of wave elevations of the sea surface from the Gauss distribution. The analysis was carried out on the basis of a model representing the reflected impulse of the altimeter in the form of a verification of functions depending on the measurements conditions, the technical characteristics of the altimeter, and the state of the sea surface. The SB errors calculated for the Sea of ​​Azov are significantly lower than those for the Black Sea. It is shown that the maximum errors $$left| {SB} ight|$$ for the Sea of ​​Azov reach the level of 1–2 cm, while for the deep-water zone of the Black Sea they are about 40 cm. The average annual error level $$left| {SB} ight|$$ for the Sea of ​​Azov is less than 1 cm, for the Black Sea −17 cm. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
