This paper gives a qualitative view of wind hazard in urban centres of southern Nigeria. It is observed that strong winds associated with rain storms at the beginning of the rainy season are a threat to urban centres as they directly affect buildings and infrastructures. Wind hazards also have indirect social and economic consequences on the communities affected. Much of the damages done to the infrastructures are as a result of inappropriate designs that have not taken into consideration the maximum wind speed in environment. This paper provides a guide to designs in wind environments for engineers in the design office. It modeled the wind speed in eight different urban centres of Nigeria and from there got the maximum design wind speed for southwestern Nigeria. The model was developed using Cook-Mayne (CM) method which adopted Monte Carlo techniques for obtaining wind load of a prescribed probability. The model gives the increase in the design speed at different calculated risks and at different structures desired. The best fitting line for Western Nigeria is given as Vmax = 90.88 + 11.5Y
