Best time to dive in Costa Brava

Optimal Diving Seasons

Peak Seasons

The best three months for diving in Costa Brava are June, July, and August. During these months, the water temperatures are warmest, ranging between 23°C to 26°C (73°F to 79°F), making for comfortable dives. Visibility is at its peak, often exceeding 20 meters (65 feet), which provides an excellent opportunity to explore the underwater landscapes and marine life. Additionally, the weather is stable with minimal rainfall, ensuring safe and enjoyable diving conditions.

Off-Peak Seasons

Diving during the off-peak seasons, such as the winter months—November to February—can have both advantages and drawbacks. On the plus side, divers will enjoy less crowded dive sites and potentially lower prices for accommodations and dive packages. Water temperatures, however, can drop to around 13°C to 15°C (55°F to 59°F), necessitating thicker wetsuits or drysuits. Visibility can also be reduced due to increased plankton blooms. Divers should be prepared for cooler weather and possibly rougher seas.
