City developments have an impact on increasing the conversion of green open spaces (GOS) to builded spaces. The reduction of GOS areas cause the increase of the air temperature in the atmosphere. One way to overcome that problems by urban forest development for micro climate improvement. The function of the urban forest will be felt if the selection of tree species fits with micro climate amelioration function. The objectives of this research were to (1) study the characteristic of urban forest which is effective for the micro climate amelioration, (2) evaluate the suitability of tree physical characters for the micro climate amelioration, and (3) determine the potention of shade trees for the micro climate amelioration. The result shows that urban forest which is effective for the micro climate amelioration have an canopy areas as much as 19927 m2 with 720 of trees. The trees at Tinjomoyo Recreational Forest, Krobokan Urban Forest, and Menteri Supeno Park have the suitability value at the range of 61–80%, while Beringin Park have the suitability value at the range of 41–60%.
