Paper addresses maximum annual values of mean wind velocity in all plain and piedmont regions of Krasnodar Krai, which were used as the basis for establishing wind loads on buildings in local code SNKK “Loads and Actions. Snow Loads and Wind Actions”. Research employs time series of anemometric measurements of wind velocities from the beginning of 1970s to 2012 extended by 13 years as compared to the time series used for developing this code. Inversion criterion was employed for assessing the significance of the linear trend of wind velocity maximums. Assessment made for the data of 29 meteorological stations showed that significant trend of increase of wind velocity with the high level of statistical certainty is present only in two cases. In half of the rest cases trend is descending, in another half trend is statistically insignificant as well as mostly descending. Combined analysis of time series of vane and anemometric mean wind velocity measurements over 1945 – 2012 demonstrated one period of significant increase of wind velocities in 1966 – 1977 and sustained decrease of these velocities in 1979 – 2012. It is shown that the database of 10 minutes mean wind velocities used for development of SNKK in 2000 does not underestimate wind pressure as compared to the values observed up to the present time.
