Snorkelling Costa Brava promises crystal-clear visibility, diverse marine ecosystems, and plenty of hidden coves waiting for your exploration.
Best Time To Snorkel On The Costa Brava
Costa Brava offers fantastic snorkelling conditions year-round, but here’s what you can expect seasonally:
- Spring (April–June): Warming waters, fewer tourists, and abundant marine life activity make spring an excellent snorkelling period.
- Summer (July–September): Optimal water temperatures around 24–26°C. Popular with tourists, so snorkel early in the day to avoid crowds.
- Autumn (October–November): Warm waters and excellent visibility, ideal for a more peaceful snorkelling experience.
- Winter (December–March): Cooler temperatures (around 13–16°C), offering tranquil conditions for snorkellers with wetsuits.
For the best balance of warmth, visibility, and fewer crowds, visit in late spring or early autumn.
