São Paulo is the largest city in Brazil, with a city population of about 11 million and almost 20 million in its metropolitan region. It is the capital of the Southeastern state of São Paulo, and also a beehive of activity that offers a jovial nightlife and an intense cultural experience. São Paulo is one of the richest cities in the southern hemisphere, though inequality between the classes typically observed in Brazil is blatant. Historically attractive to immigrants as well as (somewhat later) Brazilians from other states, it's one of the most diverse cities in the world.
June - September is winter in São Paulo. Average daytime temperatures in the month of June are 71°F/22°C and night-time temperatures are 55°F/13°C.
Brazilian Real (BRL or R$) is the local currency and is found in the following note denominations: 2, 10, 20, 50, 100. Currency can be exchanged at banks or private currency exchange stores. Rates vary between banks and stores; additional charges may apply.
Generally 110V; some hotels have both 110 and 220 volts.
São Paulo’s official language is Brazilian Portuguese, with many tourist-related service industry personnel communicating in English or Spanish.
During the day, the tourist areas are generally safe for walking; in the evening the safest neighborhoods are Jardins, Higienópolis, and the residential areas of the city. At night, it's best to avoid the quiet side streets of Centro, particularly the empty shopping streets around Praça da Sé and Bixiga. The area around the Praça da Luz is definitely to be avoided after dark.
At night, traveling by taxi is strongly recommended -- don't rely on public transportation. The U.S. State Department has reported incidences of armed robbery and widespread pickpocketing in São Paulo, though this has not been our experience. As in any large metropolitan area with great disparities between rich and poor, it's wise to observe common-sense precautions: Don't flash jewelry or cash, and stick to well-lit and well-traveled thoroughfares.
The city of São Paulo charges a 5% accommodations tax, collected by the hotel operators. This amount will be added to your bill. There are no other taxes on retail items or goods.
São Paulo follows UTC/GMT -3 hours.
