Mid-August in Euskal Herria brings an electric, unforgettable gear shift. Now is the turn of Bilbao and its iconic Aste Nagusia, the festive pulse spreads like wildfire down the coastline and deep into the valleys of Bizkaia. Summer here isn’t just a season—it’s a collective rhythm of brass bands in historic casco viejo (old town) and txosnas popping up along riverbanks, and the undeniable aroma of grilled sardinas drifting over ocean breezes.

What makes these peak August days so special is the seamless blend of coastal magic and local tradition. You can spend your morning watching traditional herri kirolak or rowing regattas along wild Atlantic beaches, your afternoon sipping a crisp sagardoa or txakoli in a lively plaza, and your evening wrapped up in world-class classical music, open-air concerts, or legendary late-night street parties (erromeria/verbenas).

From the grand farewell of Bilbao’s fireworks to the loud, every night a different show, and the proud kick-off of Bidasoa Folk 2026 in Irun, Hendaya and Hondarribia.

Pick your destination, embrace the vibrant spirit of jaias, and dive into the very best events happening across the region this week!
