Seasonal sea turtle encounter rates

Details and observation tips for each season in Okinawa

Spring characteristics: Spring is the most balanced observation season of the 1 year.

As water temperatures gradually rise, sea turtle activity also increases.

Since it is also the tourism off-season, you can enjoy observing them at a relaxed pace.

Observation tips:

• Early morning observation in clear air is best
• Choose times when the sun is not strong
• Check the tides

Observation spots recommended by veteran guides:

• Sesoko Island shallows (80% encounter rate)
• Around the rocks at Cape Maeda (70% encounter rate)
• Seagrass beds at Odo Coast (75% encounter rate)

Summer characteristics: Summer has the highest encounter rate.

Many sea turtles gather near the coast to lay eggs.

However, this overlaps with peak tourism season, so tours need to be booked early.

Points to watch out for

• Protection from strong sunshine
• Observation etiquette during busy periods
• Physical exhaustion

Advice from a local guide: "Okinawa's high summer encounter rates also attract many tourists.

By aiming for the early morning, you can enjoy a relaxed observation experience."

Autumn characteristics: Aside from typhoon season, autumn is a suitable time for observation.

Water clarity in particular reaches its annual peak, making this the ideal photography season.

Photography techniques

• Underwater camera settings

Tips for the best shots:

• Use backlighting (around 8 a.m. is best)
• Position yourself at the sea turtle's eye level
• Avoid sudden movements and approach slowly

Advice from a local photographer: "Underwater visibility is especially good in autumn. It sometimes exceeds 25m.

This is a good season for capturing a sea turtle's whole body in the frame."

Winter characteristics: Activity slows during Okinawa's winter, but fewer tourists make it a season for observing carefully and at leisure.

However, protection from the cold is essential.

Tips for protection from the cold

• Choosing a wetsuit

For water temperatures of 18–21 degrees: 5mm thickness recommended

A full suit is best

Choose a slightly snug size

Suggested time in the water

• Beginners: 30–40 minutes
• Experienced participants: 45–60 minutes
• Fully equipped for the cold: 60–90 minutes

A guide's comment: "In Okinawa's winter, we recommend shorter observation sessions and frequent breaks. In return, the quiet surroundings offer an appealing opportunity to carefully observe sea turtle behavior in Okinawa."
