Combined with the long-term observation data of three-dimensional ultrasonic anemometer at the deck of a long-span suspension bridge in the coastal area of Guangdong Province，the average wind characteristics of the wind field at the bridge site are statistically analyzed. Taking the wind speed exceeding 8 m/s as the standard of strong wind，the fluctuating wind characteristics of the bridge site are analyzed based on strong wind samples. The results show that the coastal areas of Guangdong are mainly affected by the southeast monsoon in spring and summer and the northwest strong wind in autumn and winter. The downwind turbulence intensity is obviously greater than the transverse wind and vertical turbulence intensity，and the ratio of each component is roughly Iu∶ Iv∶Iw=1∶0.86∶0.60. There is a significant positive correlation between gust factor and turbulence intensity，and the empirical formula recommended by Cao and Choi can better reflect the relationship between the two，and the empirical formula recommended by Cao is more suitable for coastal areas. Turbulence integral scale has a negative correlation with turbulence intensity. With the increase of turbulence intensity，turbulence integral scale first decreases rapidly and then tends to be stable. Based on the measured data，the empirical formula of turbulence integral scale and turbulence intensity is given，and the correlation between the two is significant. In the measured data，the downwind power spectral density is in good agreement with Kaimal spectrum，the transverse wind power spectral density is in good agreement with Von Karman spectrum，and the vertical power spectral density is in good agreement with Panofsky spectrum at high frequency band.
