Festas do Mar Cascais in Cascais
Festas do Mar celebrates Cascais's identity as a former fishing town and current coastal resort with a month of sea-themed concerts, markets and outdoor events along the waterfront each August. Scheduled across 1-31 August 2026, it turns the town's marina and seafront squares into a summer festival circuit.
Before Cascais became known for its marina, its beaches and its role as a royal-era retreat from Lisbon, it was a fishing town, and the sea that once defined its working life is exactly what Festas do Mar sets out to celebrate each August.
