Using the meteorological data of seven cities in Beijing, Tianjin and Hebei Province, the variation of surface air temperature during the long vacations of International Labor Day and National Day was analyzed to determine the climate effect of “Golden Weeks” beginning from 1999. Results show that mean and maximum temperature significantly change during the long vacations of “Golden Weeks”. An apparent increasing trend of average air temperature is found during the sevenday vacation period of International Labor Day, whereas average air temperature shows a decreasing trend during the seven days of National Day. During the long vacation of International Labor Day, both mean maximum and minimum temperatures significantly increase with a larger increase in maximum temperature. Mean maximum temperature shows weakly change in the vacation of National Day, whereas the minimum temperature significantly decreases during the same period.
