Nowadays, Surabaya experience Urban Heat Island (UHI) phenomenon because of the increase of surface temperature from 1994 until 2011. The urban structure parameters have a role in decreasing the UHI phenomenon. Rajawali is a historic area where it can be sensitive to climatic condition and urban heat island. This paper aimed to analyze the correlation of urban structure parameters toward climatic variables (as an indicator affecting UHI) in the heritage area of Rajawali. This study focuses on some urban structure parameters that are Building Coverage Ratio (BCR), Floor Area Ratio (FAR), aspect ratio (H/W), Volumetric Compactness (S/V) and land cover in the site. The analysis method is a simulation from Envi-met where simulation performed is run in March 2018. In order to check how far the urban structure affects climatic variable, the urban structure parameters are compared with each variable of climatic using the statistical package, R. For correlation analysis Pierson’s r coefficient is used. The result shows that not all urban structure parameters correlate with climatic variables in the Heritage Area. The findings of this study are expected to be the basis for designing the heritage area in Rajawali so that the design can respond to the UHI phenomenon in Surabaya.     Keywords: Urban Structure Parameters, Climatic Parameters, Heritage Area, UHI (Urban Heat Island)
