In the early stages of the rainy season the cumpizeiros perform the bioluminescence phenomenon which consists in the irradiation of a blue greenish phosphorescent light, produced by small larvae stuck to the leafs in search for food. The result is a very beautiful night show.
This park holds the largest concentration of cumpinzeiros per square metre in the whole world.
The dry season with water shortages shows during the southern hemisphere's winter, from April to September. The summer and spring seasons are very hot with temperatures ranging between 22° and 24° C. Precipitations vary from 1500 to 1750 mm a year.
