Why Season Matters
Even though Kerama is diveable all year, each season provides unique experiences:
- Water temperature changes
- Visibility can vary slightly
- Weather patterns (typhoons in summer)
- Marine life activity
- Travel crowds and accommodations
Understanding these differences can help you choose the season that best matches your preferences.
Seasonal Overview
🌸 Spring (March–May)
- Water temperature: 21–24°C
- Visibility: Excellent (20–40m)
- Conditions: Calm seas, moderate crowds
Spring offers comfortable air and water temperatures, excellent visibility, and fewer tourists than summer. It’s ideal for divers who want clear conditions without the peak-season bustle.
☀️ Summer (June–September)
- Water temperature: 27–29°C
- Visibility: Very good

🍁 Autumn (October–November)
- Water temperature: 25–27°C

Autumn is often the best overall season. Water remains warm, visibility is high, and fewer tourists make planning easier. Perfect for those wanting a balanced experience.

- Visibility: Very good
- Conditions: Quiet, peaceful dives; slightly cooler water
Winter offers calm seas and minimal crowds. While a thicker wetsuit is recommended, the relaxed pace and clear visibility make it an attractive season for divers seeking tranquility.
