Sao Joao de Petrolina in Petrolina
Petrolina runs a roughly nine-day Sao Joao program on the Pernambuco bank of the Sao Francisco River, opposite its twin city Juazeiro in Bahia, combining forro concerts with the semi-arid Sertao setting that defines the region's wine and fruit agriculture. Local reporting confirms tourism impact, but detailed programming information is limited.
Petrolina sits on the Pernambuco bank of the Sao Francisco River directly across from Juazeiro in Bahia, and the twin-city area runs a joint-feeling but separately organized June festival season built around forro, the accordion-driven dance music that gives Northeastern Sao Joao its sound.
