dos Campos and Campinas with over 30 million inhabitants as a total number. Cityscape The municipality comprises three districts: São José dos Campos — the city itself, (also the seat), Eugênio de Melo and São Francisco Xavier. The last one is known for its natural sites and ecotourism. The district of São José dos Campos is also subdivided into 2 subdistricts (São José dos Campos and Santana do Paraíba). However, for administrative purposes, the city is composed of 7 urban regions: Center, North, South, West, East, Southeast and São Francisco Xavier. Topography Highlands predominate in the northern region of the municipality with altitudes ranging from . The northern border of the municipality lies over the Serra da Mantiqueira Mountains (Mantiqueira Range), with some peaks reaching over 2000 meters (6500 ft.). The highest point in the municipality is known as 'Pico do Selado' at an altitude of 2082 meters. In the urban area, there are rolling plateaus and hills. The lowest elevation in the city (and also in the municipality) is found in the Paraíba do Sul River, at a mean elevation of 550 m. The municipality is bounded at the south by the 'Serra do Jambeiro' mountains, with an elevation of about 900m. Due to the high topographic differences among neighborhoods and the urbanization, the city now experiences micro-climates present in distant areas. The downtown tends to concentrate frequent urban heat islands, while the suburb areas get noticeably colder main temperatures. As the northern part of the city, mainly the district of Sao Francisco Xavier, mescles high attitudes and ecologically preserved areas the climate is better classified as Humid Subtropical Climate ("Cwb"). Municipality: Elevations City: Elevations . The municipality holds the São Francisco Xavier Environmental Protection Area, established in 2002. It contains part of the Mananciais do Rio Paraíba do Sul Environmental Protection Area, created in 1982 to protect the sources of the Paraiba do Sul River. Climate The climate of the city can be, perhaps, best described as a mix between the subtropical climate of southern parts of the country, the tropical climate of most of the country and the subtropical highland climate (in Portuguese: clima tropical de altitude) of neighbouring mountainous regions. Technically, the city has a humid subtropical climate with significant less precipitation during winters (transitioning between Cfa and Cwa climatic types in the Köppen classification). Winters are very mild, with average temperature in the coldest month
