Key Points

Sunday is a warm, dry wind-down — about 27°C with only 10% rain — so the open-air rodas are a safe bet, not a weather gamble.

The weekend’s big Lapa houses are closed: Rio Scenarium and Carioca da Gema both shut on Sundays, so the night moves to free, traditional samba.

Pedra do Sal’s open-air roda in Saúde runs from 18h (Visit Rio), and the dry forecast makes it tonight’s easy headline.

Bip Bip in Copacabana holds its Sunday samba from 19h — free, cash only, with the house’s no-talking, finger-snap rule.
