Best Times to Freedive: March to May and October to November

Overview: These months are considered the prime freediving season in Seychelles due to the excellent visibility, calm seas, and warm water temperatures.

Conditions:

  • Water Temperature: 29-31°C (84-88°F)

  • Visibility: Excellent, often exceeding 30 meters

  • Seas: Generally calm, making it ideal for freediving


Marine Life: During these months, the clear waters and favorable conditions make it easier to spot a variety of marine species. In October and November, there's a chance to encounter whale sharks, the gentle giants of the ocean. Remember to respect these magnificent creatures by not touching them and maintaining a safe distance.

Tips: These periods are perfect for freediving enthusiasts of all levels. The warm water means you can comfortably dive without a wetsuit or with a thin suit for added buoyancy.





South-East Monsoon: June to August

Overview: The south-east trade winds dominate this period, leading to rougher seas and reduced visibility on the south-east side of the islands.

Conditions:

  • Water Temperature: Around 26°C (79°F)

  • Visibility: Reduced, typically between 10-15 meters

  • Seas: Choppy on the south-east side, making freediving challenging

Marine Life: During this period, you might encounter jellyfish and an increase in plankton, which can affect visibility but also attract larger filter feeders.

Tips: To avoid the rough conditions, head to the north-west side of the islands where the waters are more sheltered. A 3mm wetsuit is recommended due to the cooler temperatures.







North-West Monsoon: Mid-December to February

Overview: The north-west monsoon brings choppy and rough conditions to the north-west side of the islands.

Conditions:

  • Water Temperature: Warm, around 28-30°C (82-86°F)

  • Visibility: Can vary, but often reduced in choppy conditions

  • Seas: Rough on the north-west side, better on the south-east side

Marine Life: The monsoon season can bring an influx of nutrients to the water, supporting diverse marine life, but it also means more unpredictable weather and water conditions.

Tips: Freedivers should focus on the south-east side of the islands during this period. Be prepared for rain as this is also the monsoon season, though weather patterns have become less predictable in recent years.


Special Seasons and Considerations

  • Whale Shark Season: October and November are prime months for spotting whale sharks. If you're lucky, you might also see them in June and July. Always respect these creatures by keeping your distance and not touching them.

  • Monsoon Variability: While the traditional monsoon season is from mid-December to February, recent years have shown unpredictable weather patterns. It's always good to check local weather reports and consult with local freediving operators for up-to-date conditions.





Conclusion

Freediving in Seychelles offers a unique experience throughout the year, but understanding the seasonal variations can help you make the most of your diving trips. Whether you’re aiming for the calm, clear waters of March to May and October to November, or navigating the challenging conditions of the monsoon seasons, each period offers its own set of rewards and challenges. Plan accordingly, respect the marine environment, and enjoy the underwater wonders of Seychelles!
