Urban climate is a local modification of regional climate made by the city. One of the most important variations is the thermal one. It consists in a particular spatial distribution patron of temperature in the urban area and the differences with the rural temperature.Tandil is a middle city (120.000 habitants) with a diversity economy located in the Southeast of Buenos Aires province, Argentina. It is place in the centre of Tandilia System and has a continental template climate. Urban climate studies have being developed during the past five years, but the thermal islandanalyze is a recently line of work. This article presents the first results of spatial distribution patrons of temperature in each season and during the day.The information was obtained in four campaigns, one per season and consisted in three daily measurements in four transects during typical season day. Three termohigrometers where use in each of the 33 stations of measurements. Thematic maps were made in ArcGis 9.3 ® with this information.In each season a cold island were detected, only in summer and spring heat island is present. The most important temperature difference was on the fall afternoon and the less one was on summer morning. The North and Northeast area of the city showed the highest temperatures in all the measurement.
