The risk assessment of gale damage in Beijing Olympic Games is conducted according to the 36year wind data in Beijing. The results indicate that there are more strong wind days in spring compared with other seasons, with the most in April and the lest in September. The average number of strong wind days from June to October is usually two or three with the maximum being five. By calculating the number of stations with strong wind from 1971 to 2006, the spatial distribution of risk grades of gale damage during the Beijing Olympic Games (June to October) is worked out. The risk level of gale damage is about the same over the whole Beijing area, and the high risk area spreads in the southtonorth direction with the highest risk in the south, especially the southwest, which may be attributed to the frequent summer rainstorms and the topography of the areas.
