When the genetic, soil and cultivation technique are not limiting factors, the fluctuation of yield production is affected by the climate or environmental factors. The objective of this study is to observe the water availability effect (i.e., water deficit, rainfall, and rainy days) on the sex ratio, including the models of oil palm yield production. The study was carried out from November 2016 to October 2017 in the Wilmar International Plantation Region Central Kalimantan. Analysis using the multiple regression and correlation tests, including the classical assumption test (i.e., normality, multi-collinearity, and heteroscedasticity tests) for the statistical analysis in this study. The results show that the rainfall and rainy day significantly affect the sex ratio development during 23 months before harvest (MBH) when the water deficit significantly impacts the sex ratio at 24 MBH. While the estimation of distribution monthly production, budget production, and actual production was not significantly affected. Therefore, it can be used to estimate the monthly distribution production of oil palm accurately.
