Globo Online has a few different tools that can help you plan your trip while traveling in Brazil, particularly in São Paulo and Rio de Janeiro.
Maps
Traffic: check traffic conditions on the major roads in Rio and São Paulo, which is very important during rush hour and lunch time;
Find a street: locate your destinations before leaving, so you have an idea of where you’re going;
Plan your route: use Globo’s version of Mapquest to plan your trip from point A to point B.
Weather
Check the weather before you go out, which is particularly important in the coastal cities, where many activities are weather-dependent. You can also check ocean and surfing conditions.
Language
For those with knowledge of Portuguese, Globo has an online Portuguese dictionary, which also includes verb conjugations and grammar help.
Travel
Globo has cultural guides for Rio and São Paulo, including movies, restaurants, fine & performing arts, concerts, nightlife, and sightseeing/activities.
