The paper analyzes changes in the characteristics of the group structure of surface waves during the extreme storm in the Black Sea on November 25-26, 2023. The analysis uses wave measurement data from a stationary oceanographic platform located near the southern coast of Crimea. The group structure characteristics are calculated using two procedures based on the Hilbert transform and the SIWEH function. The temporal variations in the group factor and the number of waves in a group are construct
