An attempt was made to study the impacts of weather components viz., temperature, humidity and rainfall on bunch production and floral characteristics of coconut (Cocos nucifera L.) during two consecutive years (2003-2005) at HRS, Mondouri, BCKV, with five cultivars namely ‘East Coast Tall’, ‘Hazari’, ‘Jamaican Tall’, ‘Java’ and ‘Zanzibar’.‘East Coast Tall’ produced the largest bunch followed by ‘Java’ and ‘Zanzibar’. The longest inflorescence with the greatest length and number of spikelets were recorded with ‘Hazari’. Maximum female flower was produced with ‘Java’ but highest nut set was recorded with ‘Zanzibar’. There was no seasonal impact on the length of the spikelet bearing portion, stalk length and spikelet length. The greatest number of female flowers was recorded during May followed by September but the coolest months (December-January) induced the highest nut set as compared to dry (May) and rainy months (June-September). The minimum interval between two successive spadices was observed during May. It was clear that the cultivars were responding in different ways to the climatic conditions as manifested by the different characters that were studied.
