A local climate with special spatial structure (e.g. heat island) is formed within the settlement compared to outside open spaces. We presume that these climatic modification affects the phenological and phenometrical properties of the urban vegetation. For this study we have chosen two medium-sized Hungarian cities (Szeged and Debrecen), with urban areas over 30 km2 and with population between 160 and 200 thousand. The phenological and temperature observations have been taken in grid networks in spring of 2003. As a good observable plant, forsythia (Forsythia suspensa) was the object of our examination because this species occurs in the 60-70% of the areas of both cities. The time of the different phenological phases was monitored in a daily fashion. According to the results there is significant correlation between the spatial distributions of the timing of these phenological phases and of the intensity of the urban heat island. The strongest correlation occurs between the UHI intensity and the date of 100% flowering in Debrecen.
