This paper presents a micrometeorological study on the environmental benefits of trees in Federal Government Girls' College Akure, Ondo State, Nigeria. Temperatures under three different surfaces (under trees and among different tree species, bare-ground and asphalted surfaces) within the school were measured. The temperature under commonly planted trees such as Neem (Azadirachta indica), Gmelina (Gmelina arborea) and Mango (Mangifera indica) found on the school compound alongside bare-ground (no vegetal coverage) and asphalted road surfaces were measured in degree Celsius for a period of six weeks. Infrared thermometer and Digital Hygrometer was used to collect surface and air temperatures respectively and their averages calculated. The GLOBE Observer App for trees was used to obtain tree height and circumference and to submit all data collected for the calculated mean average of air and surface temperatures for different surfaces. Data collected were analyzed using frequency, percentage, bar chart, and pie chart. The study showed that there is a temperature variation under different surfaces. Under the trees recorded lowest mean temperature of 23°C followed by bare-ground with 28°C whereas asphalt surface recorded the highest mean temperature of 53°C. The temperature under different tree species shows that trees with bigger crown and broad leaves had lower temperatures. Mean temperature under the Mango tree was 28°C while under the Neem tree, mean temperature was 32°C. Keywords: Temperatures, Asphalt, Trees, Canopy, Environment, Micrometeorological, Urban.
