Coastal regions exhibit distinct temporal patterns in meteorological variables and renewable energy resources due to the interaction of atmospheric, marine, and thermal processes. This study aims to analyze the microclimatic characteristics and coastal wind patterns of Kish Island and investigate their relationship with wind and solar energy potential. Hourly air temperature, wind speed, and solar radiation data were analyzed over a one-year period in 2024, comprising 8,760 records. Following data quality control, air density was calculated using the ideal gas equation under the assumptions of dry air and constant atmospheric pressure of 101,325 Pa, and wind power density was determined by accounting for hourly variations in air density. In addition, the Weibull distribution, the correlation between wind speed and solar radiation, and the diurnal pattern of wind speed were investigated. The annual mean air temperature, wind speed, and solar radiation were 28.22 °C, 3.79 m/s, and 224.20 W/m², respectively. The annual mean wind power density was estimated at 72.11 W/m². The Weibull distribution, with a shape parameter of 1.794 and a scale parameter of 4.276 m/s, showed a good descriptive fit to the observed wind-speed distribution ((R^2 = 0.993)); however, the Kolmogorov–Smirnov test rejected the hypothesis of complete agreement between the theoretical and empirical distributions ((p < 0.001)). The Pearson correlation coefficient was 0.057, while the complementarity index, calculated according to the formulation presented in the methodology section, was 0.472. The mean wind speed increased from 3.26 m/s at 07:00 to 4.40 m/s at 15:00.
