Land use change is one of the key factors affecting local and regional climate patterns. This study investigates how different land covers (grassy and concrete) impact surface and air temperatures in Nyali area, Mombasa. The research aims to determine temperature variations, assess the role of land cover in temperature regulation, and evaluate contributions to the urban heat island (UHI) effect. Data was collected using Digital Hygro-Thermometers and Extech Mini IR Thermometers at three different time intervals across selected locations representing the two land cover types. The study found that concrete surfaces exhibited higher temperatures than grassy areas, significantly contributing to urban heat retention. The findings suggest that impervious surfaces increase temperature rise, affecting human comfort and urban climate. The research concludes that urban planning should include more green spaces to mitigate UHI effects and recommends policies promoting sustainable land cover management. Keywords: Land use change, temperature variation, urban heat island, climate impact
