CFD simulation is utilized to analyze the wind environment and outdoor comfort surrounding a typical super high-rise building cluster in Zhuhai by using a software PHOENICS with consideration of local climatic conditions. The results are as follows: 1) The direction of dominant wind changes from season to season in the research district

which is north (N) in winter

south-southwest (SSW) in summer and east-northeast (ENE) in the transitional season

resulting in the variations of the wind and comfort in down ground and building facade. 2) When the wind is blowing from the high-rise buildings to the low-rise buildings

the floor ventilation and comfort between the high-rise buildings and the low-rise buildings are poor

because of blockage effects. In the meanwhile

the well ventilated areas

for example the upwind side and both sides of the high-rise buildings

are more comfortable comparably. 3) When the wind blows from the lower buildings to the high-rise buildings

the ventilation conditions of the spaces between buildings are better

since the flows pass through the lower buildings and get amplified. And the ventilation and comfort of the facade are better in comparison with the situation when wind blows from the high-rise buildings to the low-rise buildings. 4) As the wind speed increases with the increase of height

people will feel uncomfortable in the upwind face and the corner of both sides of the high-rise buildings and the ventilation corridor

where wind speed exceeds Grade 3.
