San Fermín 2026 begins in Pamplona with 204 hours of nonstop festivities. The Consistorial Square fills early as temperatures climb, and authorities activate an orange alert for heat. Medical staff lead the traditional chupinazo.
San Fermín 2026 officially opened in Pamplona at midday, as thousands crowded into the Consistorial Square under a rising heatwave. The city, dressed in its signature white and red, saw anticipation build from early morning, with the municipal police managing access points as the plaza filled to near capacity well before the scheduled start.
This year, the honor of launching the chupinazo fell to Clint Jean Louis Fernández, subdirector of the emergency service, and Araceli Sergio Aguilera, nurse from the Tafalla mobile ICU. Their words echoed across a crowd of 12,000, marking the start of 204 hours of uninterrupted celebration. According to Aemet, temperatures had already reached 24°C by late morning, with forecasts predicting a peak of 33°C at noon and up to 39°C by late afternoon. The agency issued an orange alert for high temperatures in the Navarre capital, raising concerns for both participants and emergency services as festivities began.
By mid-morning, the old town’s streets had transformed into a sprawling open-air dining area, with locals and visitors gathering for traditional San Fermín breakfasts. The festive atmosphere was palpable, but so was the heat, which continued to climb as the day progressed. Organizers and authorities urged caution, especially for those planning to remain outdoors for extended periods.
The Consistorial Square was nearly full two hours before the official start, reflecting the strong desire to participate after a year of anticipation. The excitement was evident among the crowd and the chosen chupinazo launchers, who expressed their emotion in an interview with Diario de Navarra. The day began with a refreshing 18°C, but the rapid temperature rise added a layer of urgency to preparations and safety measures.
While the chupinazo signals the start of the festival, the day’s program extends far beyond the opening ceremony. Streets across Pamplona are set for a week of events, meals, and gatherings, with the city’s emergency and municipal services on high alert due to the weather. The scale of the festivities and the heat risk have prompted organizers to reinforce medical and hydration points throughout the city.
San Fermín is not only a local highlight but also draws national and international attention. As noted in recent coverage of the festival’s expanded live broadcasts and bull runs, Pamplona’s celebration remains a focal point for Spanish culture and tourism. The combination of tradition, large crowds, and extreme weather this year underscores the importance of coordinated public safety efforts.
San Fermín’s origins date back centuries, with the chupinazo now recognized as the symbolic start of one of Spain’s most renowned festivals. The event’s duration—204 hours of continuous activity—places unique demands on city infrastructure, emergency services, and hospitality sectors. The 2026 edition stands out for its early heatwave, testing both the resilience of participants and the readiness of local authorities. As festivities unfold, attention remains on how Pamplona manages the balance between celebration and safety in challenging conditions.
