Paraguay experiences a subtropical climate in the Paraneña region and a tropical climate in the Chaco. The Paraneña region has a humid climate, with abundant precipitation throughout the year and only moderate seasonal changes in temperature.
The Río Paraguay has a total course of 2600 km, 2300 km of which are navigable and 1200 km of which either border on or pass through Paraguay.
Even though Paraguay maintains a strong indigenous culture with its descendants of the Guirani people, the Spanish Empire left its mark on the region and 90 percent of the population are practicing Roman Catholics. This is evident in the traditional Catholic festivals, such as Dia de San Blas and the largest festival in Paraguay, Carnival.
