| Abstract: | The fluctuation of the water table east of La Pampa province and northwest of Buenos Aires province, Argentina, influences
agricultural production in the region because it is closely related to the alternation of dry and wet periods. Sea-surface
temperature (SST) anomalies have been used as predictors to forecast atmospheric variables in different regions of the world.
The objective of this work is to present a simple model to forecast seasonal rainfall using SST distribution in the Pacific
Ocean as a predictor. Once the relationship between precipitation and water-table fluctuations was established, a methodology
for the prediction of water-table fluctuations was developed. A good agreement between observed and predicted water-table
fluctuations was found when estimating water-table fluctuations in the summer and autumn seasons.
