Rainfall in the Amazon rainforest varies significantly by region and season. On average, the Amazon receives about 1750 to 2000 millimeters (69 to 79 inches) of rain annually. Some areas, particularly near the equator, can receive much more, with certain spots exceeding 3000 millimeters (118 inches) per year.
Rainfall typically occurs year-round, but there are distinct wet and dry seasons in various parts of the Amazon. In general, it can rain almost every day in some locations, leading to hundreds of rainy days per year. However, the exact number of rainy days can depend on specific geographic conditions and the time of year.
