The Urban Heat Island (UHI) has never considered as an issue in urban planning for Chiang Rai municipality where is considered an rapid economic growth with urban development. According to the result, at 15:00 h, it was found that the temperatures at some moving observed points was slightly increased and higher than the temperatures at the fixed weather station about 3–4 ℃ while, at 20:00 h. It was found that the temperatures at most moving observed points was obviously higher than the surrounding areas, especially in business areas which were 5–6 ℃. The thermal differences (Urban Heat Island: UHI) varied directly with the man-made structures but they were inversely affected with the natural areas following Y = 0.0393X1 – 0.7533 (R2 = 0.8996) and Y = -0.0393X2 + 3.1765 (R2 = 0.8996) equations.
