🇧🇴Bolivia

Spanning 9°41′ to 22°53′ south latitude, landlocked Bolivia sits in central South America with an extreme altitudinal range from the Andean Altiplano and high peaks—including Sajama at 6,542 meters and Illimani at 6,438 meters—descending through the central Yungas slopes to the Amazon lowlands in the northeast and the Gran Chaco plains in the southeast. This dramatic elevation gradient produces the country's complete Köppen climate spectrum, from polar tundra and alpine conditions on the high cordilleras to tropical rainforest in Pando and Beni departments and hot semi-arid steppe across the southern Chaco.

La Paz at 3,640 meters averages around 9°C year-round with daytime highs near 17°C and nighttime lows around 1°C; the Altiplano experiences heavy diurnal swings and frost from July through August. Santa Cruz in the lowlands enjoys tropical warmth averaging 24 to 26°C, while Trinidad in Beni receives over 1,800 millimeters annually. Lake Titicaca moderates the surrounding microclimate.

Surazo cold fronts—southerly winds—can drop temperatures by 15°C within days even in the lowlands; the rainy season runs December through March. ENSO cycles strongly influence Bolivia: El Niño brings Altiplano drought, La Niña triggers Beni floods. Andean glaciers have retreated rapidly; Chacaltaya disappeared entirely by 2009.
