Abstract The dynamics of air temperature cause thermal comfort to be unstable in the context of an urban micro-climate. One of the places affected by the urban micro-climate is the campus of Unissula. It lies on the main transportation route of the north coast of Central Java. To create a comfortable space in the campus environment, a local scale air temperature control method is required, one of which is the provision of green open spaces (GOS). Scenarios for providing green open space based on micro-climate dynamics must be developed to create thermal comfort. This study aimed to identify and analyze the correlation between micro-climate and thermal comfort based on the existing parameters. The research methodology employed a rationalistic quantitative deductive approach with micro-climate and thermal comfort variables, as well as rationalistic descriptive analysis technique. According to the findings of this study, the comfort of Unissula campus meets the criteria for morning air temperature of 25.42°C, daytime 31.35 °C, evening 29.92 °C. The morning humidity is relatively 73.92%, the daytime is 51.50%, and the evening is 60.57%. The thermal comfort level is moderately partly comfortable.
