The relief is predominantly marked by undulating topography of the type-hill, and much of the city is set in a valley, a fact that favors the development of mountain-valley breeze circulation. This paper aims to characterize the mountain-valley breeze from wind data obtained by an automatic weather station located on the campus of the Federal University of Itajubá. The mountain breeze occurs between 15-16 local hour (LH) showing its maximum intensity between 21-22 LH, while the valley breeze occurs between 07-08 LH with maximum intensity between 11-14 LH. The results show that the mountain breeze is more persistent, which may be associated with the influence of the effect of heating for the horizontal pressure gradients between the valley and the mountains.
