Tropical locations are near the equator. Some tropical areas are wet all year, while other areas experience a wet/dry climate caused by shifting wind patterns. Wet/dry tropical climates are found in areas like northern Australia, the African savanna, and portions of northern Brazil. 

Signs of Rainy Season

In tropical climates, temperatures are warm all year. The tropics rarely become unbearably hot, instead remaining within 77 degrees Fahrenheit. During the dry season, temperatures dip about ten degrees. Subtle changes in temperature cause the wind to develop. The wind brings rainstorms. 

Although most of the year, the region is hot and dry, gusts of wind from the ocean occur regularly enough to cause a pattern. The dry season is typically longer than the wet season. When winds pick up and carry ocean water, tropical regions experience monsoons, water cyclones, and heavy rain. The rainy season has begun. 

Benefits and Drawbacks of Rainy Season

Violent storms and rushing water might not seem beneficial. However, despite floods and other disruptions, tropical regions have developed alongside their seasons, and natural grasses and shrubs prevent excessive erosion. The animals that live in tropical regions, like zebras, wildebeests, and hyenas survive by hunting or by eating grasses.

The rainy season’s precipitation fuels grass growth, suppresses dust and reinvigorates watering holes and reservoirs. Unfortunately, if the human-made infrastructure cannot withstand changes in weather, then humans might not make it through a rainy season without risks to buildings, agriculture, and lives.

Island regions are most vulnerable to flooding and monsoon winds. Inland areas still experience flooding due to overflowing rivers and soil saturation. If you live in or travel to tropical locations during the rainy season, expect difficulties traveling. 

The Rain Season Cycle

Since the rainy season in the tropics occurs annually, rainfall is highly predictable. In tropical locations, visitors and locals can expect the rain season to begin in May and end in August. June and July experience the most rainfall, with as much as 25 inches of rain falling in just three months. 

Remember, not every tropical location experiences wet/dry seasons. Many tropical locations are always wet. It rains a bit each day, but the temperatures remain warm and comfortable.
