Weather and Clothing: Day temperatures vary between 23° C (73° F) and 30° C (86° F), with relative humidity ranging around 65-75%. Night temperatures usually drop to around 18° C (65° F). Clothing should be light. Since most meeting activities will be held in air conditioned rooms, but a long-sleeve shirt could also come in handy. Sunblock products, sunglasses and a sport-cap are strongly recommended for outdoor activities.
Currency: No place in general accepts payment in US$ or € and it should not be assumed that traveler’s checks will be accepted in stores. Credit and Debit cards like MasterCard, Visa and American Express, this last one in less extension, are widely accepted by almost all restaurants, hotels, bars, and shops, and including street kiosks; it is advised to ask before consumption. Cash machines with the Plus or Maestro signs allow cash withdrawals in local currency with direct access to the user account in a foreign bank, this is the suggested best conversion rate.
Health: No extra precautions needed. The region is free from any tropical diseases and has an international environmental level. An international health insurance is, however, highly recommended as the organization will not be able to cover healthy emergencies.
Yellow fever vaccination is currently recommended before visiting some interland regions. Please note that a yellow fever vaccination takes approximately 10 days to become effective.

If there is any doubt about the need for vaccinations, please contact the nearest Brazilian Embassy or Consulate
