Mid-August in Euskal Herria brings a electric, unforgettable gear shift. As Donostia reaches the grand finale of its iconic Aste Nagusia, the festive pulse spreads like wildfire down the coastline and deep into the valleys of Bizkaia and Álava. Summer here isn’t just a season—it’s a collective rhythm of brass bands in historic cascos viejos, 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 Donostia’s fireworks to the loud, proud kick-off of San Roque celebrations in Portugalete and Laudio—and the buzz building ahead of Bilbao’s own takeover—this week is loaded with unforgettable culture.

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