Urban heat island (UHI) intensity is the characteristic warmth of both the atmosphere and lithosphere in urban areas compared to its rural surrounding areas. This study observed the seasonal dynamics of UHI in Coventry city. ArcGIS was used to collect the land surface temperature (LST) of different seasons; summer, autumn, spring and fall using the peak month to represent each

The data was collected for a period of 11years that is 2004-2014. The study revealed that there was no regular pattern of UHI across the four seasons, however, it was discovered that there was a marginal increase in temperature in some regions during the seasons. To mitigate UHI effects this study recommends the planting of trees to moderate the microclimate as well as the use of green roofs to absorb more of CO² thereby modifying and regulating the climate. Contribution/Originality: This study contributes to the existing literature on urban heat Island Intensity. Using ArcGIS and land surface temperature, the study observed the seasonal dynamics of UHI intensity in Coventry City with a marginal increase in temperature in some seasons; it therefore recommends the planting of trees to moderate the climate.
