Climate change frequently generated extreme meteorologic event. The temperature difference between urban and its adjacent rural area had been defined as Urban Heat Island(UHI). The UHI during nighttime associated with high humidity condition introduces inconvenient living condition during Monsoon season. The generation of rainfall event and intensity of UHI had been known to counter reciprocal due to the apparent rainfall disturbance to vertical temperature profile. The hydro-meteorological data collected during summer season between 2013 and 2022 was used to evaluate the UHI intensity in Busan, South Korea. The impact of rainfall generation pattern was analyzed to configure the relationship rainfall and nighttime UHI. The results were derived that the temperature difference showed the characteristics of each year rather than the regular form.
