The rainy season, or monsoon season, is the time of year when most of a region's average annual rainfall occurs. It usually lasts one or more months.<ref>Glossary of Meteorology (2013). Rainy season.

Under the Köppen climate classification, for tropical climates, a wet season month is defined as a month where average precipitation is {{safesubst:#invoke:convert|convert}} or more.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In contrast to areas with savanna climates and monsoon regimes, Mediterranean climates have wet winters and dry summers.

When the wet season occurs during a warm season, or summer, precipitation falls mainly during the late afternoon and early evening . In the wet season, air quality improves, fresh water quality improves, and vegetation grows substantially, leading to crop yields late in the season. Rivers overflow their banks, and some animals retreat to higher ground. Soil nutrients diminish and erosion increases. The incidence of malaria increases in areas where the rainy season coincides with high temperatures. Some animals have adaptation and survival strategies for the wet season. Often, the previous dry season leads to food shortages in the wet season, as the crops have yet to mature.
