This study was undertaken to investigate the relationship between rainfall and temperature characteristics and Coffee productivity. Daily rainfall and temperature and production data of Sixteen years were used for analysis. Correlation, regression, variability and trend were analyzed by Instat V3.37 and XLStat software. Seasonal and annual rainfall totals were highly variable. Pearson correlation revealed belg rainy day had positive strong correlation with coffee yield whereas end date, kiremt rainy day, kiremt rainfall total, belg rainfall total and length of growing period had positive moderate correlations. However, onset date had negative moderate correlation. Moreover, belg and kiremt mean temperature showed negative strong correlation. Influence of rainfall and temperature variability on coffee productivity was statistically significant (P=0.03). In the future, due to the expected impacts of rising belg and kiremt mean temperature, late onset and shortening of length of growing period and weakening of kiremt rainfall amount in general, productivity of Coffea Arabica L. is expected to decrease in the study area. Therefore, there is a need for more research on suitable coffee shade, drought and high temperature resistant varieties, water conservation strategies and moving coffee establishments at higher elevations.
