Rapid urbanization across Lagos, Nigeria has driven extensive land cover modifications with significant climatic impacts. This study analyzed interlinkages between land use land cover (LULC) transformations and land surface temperature (LST) shifts in the intensely developing Lagos suburb of Ikorodu from 1991-2021 utilizing robust geospatial techniques. Multi-spectral Landsat 5, 7 and 8 data enabled reliable LULC classification into five covers using a Random Forest algorithm. Subsetting the Ikorodu area facilitated localized change analyses across 1991, 2001, 2011 and 2021. LULC changes significantly impacted regional microclimates by altering surface energy budgets. Replacing vegetation with constructed materials increased LSTs while diminishing humidity via lower transpiration. Quantifying alteration magnitudes and spatial patterns provided crucial historical perspectives on urban expansion and climatic changes. Over 30 years, built-up area rose from 14% to 65% while vegetation declined from 52% to 9%, with LST increasing from 23.13°C to 27.21°C. Statistical analyses indicated LST strongly, and positively correlated with a Built-Up Index. Cooling prevailed on semi-rural peripheries with more intact vegetation. This research demonstrates and models LULC-LST interlinkages over years of swift development around Lagos, delivering a framework for crafting sustainable growth policies and balancing modernization goals with ecological stability. Explicit urban heat island effect mitigation strategies combining infrastructural adaptations and green space retention are recommended to promote regional climate resilience.
