The traditional São João of the city of Porto, in Portugal
In fact, the party starts early in the afternoon of 23 June and usually lasts until the morning of 24 June. The traditional attractions of the night include street concerts, popular dancing parties, jumping over flames, eating barbecued sardines, Caldo verde and meat, drinking wine and releasing illuminated flame-propelled balloons over Porto's summer sky.
At midnight, the partygoers make a short break to look at the sky at Saint John's firework spectacle. The show is increasingly sophisticated with the fireworks being associated with themes and multimedia shows. The party has sacred roots but is also mixed with pagan traditions, with the fireworks embodying the spirit of tribute to the Sun.
The firework are the climax of the event and mark the end of the official festivities. Yet, it is quite common for citizens of Porto to keep celebrating until 3 or 4 in the morning. Some take it further, staying up until the first hours in the morning. They walk from Porto's riverside core - Ribeira (for instance the parish of São Nicolau- up to the seaside in Foz (parishes of Foz do Douro and Nevogilde) or in the nearby suburb of Matosinhos where they wait for the sunrise near the sea, and sometimes, take a bath in the ocean.
