Bolivia's climate varies drastically with altitude and from one climatic zone to another. It ranges from humid and tropical to cold and semiarid. In most parts of the country winters are dry and summers are somewhat wet. Despite its tropical latitude, the altitude of cities like La Paz keeps things cool, and warm clothing is advised year-round. The summer months in Bolivia are November through March. The weather is typically warmer and wetter during these months. April through October, the winter months, are typically colder and drier.
Bolivia, named after independence fighter Simon Bolivar, broke away from Spanish rule in 1825; much of its subsequent history has consisted of a series of nearly 200 coups and counter-coups. Comparatively democratic civilian rule was established in the 1980s, but leaders have faced difficult problems of deep-seated poverty, social unrest, and drug production. Current goals include attracting foreign investment, strengthening the educational system, and waging an anti-corruption campaign.
The current President is Evo Morales who won majority in a 2005 election and inaugurated at the historical Tiwanaku archaeological site. Morales and his party, the Movement for Socialism, were re-elected in 2009, with another majority. There are often large protests in Bolivia considering issues like environmental protection, logging, hydrocarbon extraction, auto imports, mining, construction of highways, as well as other issues. These protests often cause the shutdown of streets in La Paz, specifically the area surrounding the Plaza Murillo, and the creation of blockades along major inter-city travel routes. If travelling between cities by bus it can be common for the trip to be stalled by several hours due to these protests.
