The use of vegetation in cities is one the most promising strategies for urban climate change adaptation and mitigation. Tree shade influences heat storage from surfaces reducing long wave radiation emission which directly affects people. People 's perception depends more on insolation temperature surrounding objects than air itself. There a need analyzes that include combined effects physical human variables thermal comfort, as well location-based studies to address its climatic social conditions. In order compare effect trees microenvironmental perceived we measured parameters performed structured interviews three downtown streets Montevideo, Uruguay, had sections with without four dates during summer. Generally, people surveyed under both treatments stated they did not feel fully comfortable due summer heat, but proportion who feeling comfort tree was double unshaded sections.The seasonal ARIMA analysis supported reduced by radiant temperature. By using statistical decision methodology combines all same analysis, found greater impact personal people's preferences. We also identified gender significant variable preferences, where 46.4 % females preferred slightly colder environment.
