The throughfall, stemfiow and interception losses of rainfall from coconut (Cocos nucifera Linn.) were quantified based on 108 days of storm records in a high rainfall region at Pelicode. The coconut has a storage capacity of 0.4 mm and the observed interception losses from it were up to 10 mm per storm. The relationship, throughfall (mm) = -0.441+ 0.875 X Rainfall (mm) (r= 0.943, at 0.01 level) has accounted for 89 per cent in the through fall from storm rainfall. The stem flow was very low and its relationship with storm rainfall was; stemflow X 10-3mm =-22.154+23.629 X Log Rainfall (mm) (r= 0.683, at 0.05 level). The influence of wind direction on the lateral distribution of throughfall below coconut canopy was also quantified.
