To study the effects of urban landscape element characteristics on air temperature around street. Air temperature is an important factor of thermal comfort. Changes in air temperature affect thermal comfort which is one of healthy city indicators. The understanding of the characteristics of urban landscape element and their effects on air temperature will guide landscape architect to a proper design of a landscape around street concerning not only aesthetic but also thermal comfort. The method of this research is comparing temperature data of eight different observation points along a cross section of a street and surrounding landscape. Each observation point consists of different urban landscape element characteristics and environmental conditions. The data are recorded in15 minutes interval from 7.00 a.m. to 5.00 p.m. to compare differences throughout the period of recording. The study shows that different urban landscape element characteristics result in different air temperature in each location. The average highest temperature point is at the east of street median area, which is an open area without tree cover. The average lowest temperature point is at the area in front of the building with a large tree cover. The different temperature is 1.88 ํC. Pertaining to themal comfort, a design of landscape around street need to have tree cover to reduce radiation from the sun and a proper selection of a landscape materials in term of proper albedo value, and vegetative surface cover.
