San Borja has a tropical monsoon climate, type (Am) in the Köppen classification system bordering on a tropical rainforest climate. Rain is plentiful but divided between a distinct wet and dry season. Like many areas in Bolivia and Latin America generally, San Borja is subject to considerable fluctuations in seasonal and annual precipitation, particularly as a consequence of climate-change related anomalies.
