Abstract - The objective of this work was to determine mean wind direction based on daily observations, from 1968 to 2000, obtained at 07h, 14h and 21h in Campinas, São Paulo State, Brazil. The data set was recorded by an Anemógrafo Universal installed at 10 meters high. The predominant wind direction at 7h was SE, with higher frequency for the periods August, September and October. The predominant wind direction at 14h was NW with 23,6% of the annual events. At 21h the predominant wind direction was SE, with monthly higher frequency in the 48,9%. The average of three observations showed that the prevailing winds occurred from SE, with higher frequency for the periods April, August, October and November.
