Can Tho city is currently undergoing a rapid urban sprawl process which has well-documented negative consequences for society and human beings, including the loss of greenspace, spatial-temporal change to urban surface temperatures, and an intensification of the surface urban heat island phenomenon (SUHI). Surface urban heat island describes surface temperature differences between urban and surrounding rural areas, which is a vital concern in urban and urban climate studies. SUHI effect is a most crucial issue, as its generation and evolution are closely related to social and economic activities. The surface urban heat island intensity (ISUHI) is determined as a difference between the LST of the UHI areas (LSTurban) and the temperature in rural areas (LSTnonurban).  The research investigated the SUHI using the Landsat 8 imagery and the land use map in Can Tho city in 2019. The strong intensity of SUHI (3-6oC) was found within urban areas, a few central districts are facing the increasing heat island trend. The research outcomes provide an important practical basis to encourage maintaining green space in long-term urban planning in the future, heat mitigation, assessment of health impacts, and energy load estimation.
