Abstract: Rainfall forecasting is imperative for agricultural planning, water resource management and adaptation to climate change. This study presents a detailed analysis of monthly rainfall forecasting in the city of Beira, Mozambique, using time series models. Statistical tests were applied, including Shapiro-Wilks for normality, Mann-Kendall for detecting trends and Fisher for identifying seasonality. The SARIMA (1,1,1)(1,1,2) model was employed for future projections, and its performance was evaluated using the AIC (Akaike Information Criterion), BIC (Bayesian Information Criterion), RMSE (Root Mean Square Error) and MAE (Mean Absolute Error) criteria. The results indicated that the SARIMA (1,1,1) (1,1,2) model exhibited the optimal performance, accurately capturing the seasonality of rainfall. The results of this study provide a relevant scientific basis for climate mitigation policies and resilience strategies in the coastal region of Mozambique.
