Portugal is a country deeply connected to its heritage, and nowhere is this more apparent than during its lively summer festivals. When the warm season hits, Lisbon and Porto burst into celebration, the biggest ones honoring saints Santo António and São João. The long-awaited Santos Populares season kicks off in Lisbon with Festas de Santo António before irradiating Porto with wine, music, dance, and partying.

Santos Populares: A Bit of History

Long before the lively street parties and colorful decorations we know today, the Santos Populares (Popular Saints) celebrations had deep religious roots. These festivals trace back to ancient pagan traditions honoring the summer solstice, which later merged with Catholic customs as Christianity spread across Europe. In Portugal, this blend of old and new gave rise to vibrant festivities dedicated to three beloved saints: Santo António, celebrated on June 13th, and São João, celebrated on June 24th.

What began as solemn religious observances gradually transformed into a month of community-wide celebrations, mixing faith, folklore, and the pure joy of summer. Neighborhoods would gather to honor their patron saints with street processions, food, music, and dancing. Over time, the festivities became as much about socializing and enjoying the warm nights as they were about religious devotion.

Honoring Santo António

In Lisbon, June is synonymous with Santo António. Every year, the city’s historic districts — like Lapa, Santos, Bica, and Graça — become a colorful maze of garlands and twinkling lights. Friends and families gather to share traditional dishes such as bifanas, caldo verde, and, of course, freshly grilled sardines.

It started as a religious observance, but it has now blossomed into a social highlight, blending old customs with modern festivity. Whether you’re a local or a curious traveler, this is the perfect time to immerse yourself in Lisbon’s authentic street culture.

If you’re thinking of visiting Lisbon, plan your trip to mid-June, during Santos Populares, and celebrate with the locals! The streets will be packed and the nights noisy, but who doesn’t like to party once in a while?

The Magic of São João

Further north, Porto becomes the heartbeat of celebration during the night of São João – and a few parties across the whole month too. On June 23rd, the city transforms into an open-air festival filled with folk music, dancing, and spectacular fireworks over the Douro River. One of the quirkiest traditions?

Locals and visitors gently tap each other on the head with colorful plastic hammers, adding a lighthearted twist to the night’s excitement. As dawn breaks, many make their way to the beach for a refreshing swim, continuing the celebration well into the next day. São João has grown into one of Porto’s signature attractions, drawing crowds from all over the world.
