 The second biggest Pride Parade in Brazil is Rio de Janeiro Gay Pride Parade, numbering about 2 million people, traditionally taking place in Zona Sul or Rio's most affluent neighborhoods between the city center and the world-famous oceanic beaches, which usually happens in the second part of the year, when it is winter or spring in the Southern Hemisphere, generally characterizing milder weather for Rio de Janeiro (about 15°C in difference), except for occasional stormy cold fronts.The Rio de Janeiro Gay Pride Parade and its associated events are organized by the NGO Arco-Íris (Portuguese for "rainbow").The group is one of the founders of the Associação Brasileira de Gays, Lésbicas, Bissexuais, Travestis e Transexuais (Brazilian Association of Gays, Lesbians, Bisexuals, Transvestites (this word used as a synonym for transgender persons in Brazil) and Transsexuals).
