This paper analyses and standardize the urban heat island (UHI) and urban dry island (UDI) effects in Matsuyama plane, focusing on the Local climate Zones (LCZs). LCZs classifies the landscape into homogeneous types based on structural type, land surface cover, materials used and human activities. This standard classification has made urban studies more meaningful and easy to compare the results with various cities globally. The LCZ map for Matsuyama was created using Landsat images, Google Earth and SAGA-GIS software. Four out of twenty-five in-situ meteorological stations network available in Matsuyama plane for different atmospheric studies were selected to represent the unique LCZ area each. UHI favourable days (August 1-6) were selected using Japanese Meteorological Agency (JMA) data. The results show LCZ with the compact mid rise building were on average 0.6°C cooler at day time and 2°C warmer at night time than LCZ with low plants. The result also shows that LCZ with the compact mid rise building were on average 2.5% dryer at daytime and 1.25% dryer at night time than LCZ with low plants.
