The air temperature-reducing effects by irrigation reservoir in urban area was investigated at Ilwol Pond (IWP). Air temperature and humidity data were observed at 10minute interval from September 1th, 2008 to August 31th, 2009. Air temperature of IWP and Sumsung Apartment (SAT) were analyzed to examine air temperature-reducing effects by IWP in terms of diurnal and seasonal variation. As a result, the average air temperature difference between IWP and SAT was $0.6^{\circ}C$ and the nighttime shows more air temperature-reducing effects. The dominant air temperature-reducing effects by IWP occurred at fall night and summer daytime. However, the air temperature-reducing effects by IWP is lower to that by Arboretum (ARB).
