In aerodrome runway design, wind climatology must be considered to reduce the potential for crosswinds and headwinds, which can lead to accidents and flight delays. In this study, using sixteen-directional polar wind roses, the Utilization Coefficient of the current Bandar Abbas airport runway (Runway 03-21) was calculated for two statistical periods: 1982–2021 and 2024–2050, considering allowable crosswinds (13 knots per hour) using the FAA method.For this purpose, the SDSM method and CanESM2 data were employed, based on three RCP scenarios (RCP2.6, RCP4.5, and RCP8.5), to examine the wind direction and speed at the Bandar Abbas station until 2050. Then, daily sixteen-directional wind roses were studied for the mentioned statistical periods.Results showed that the utilization coefficient of the current runway at Bandar Abbas airport in the 1982–2021 period was 94.04%. Additionally, forecasts indicated that by 2050, the utilization coefficient of the current runway would increase by 2.41%, 1.82%, and 1.97% under RCP2.6, RCP4.5, and RCP8.5 scenarios, respectively. Findings also revealed that compared to the 1982–2021 period, the maximum daily wind speed in the 2024–2050 period would decrease in all seasons except summer, while the average wind speed in all seasons would decrease by less than one knot.
