Crystal Clear Waters Throughout the Year

Water temperatures vary seasonally:
- Spring (April–June): 22–26°C – calm seas and moderate crowds, ideal for beginners and underwater photography.
- Summer (July–September): 27–30°C – peak season with vivid tropical fish and active turtles.

Understanding these conditions helps divers plan their trip to make the most of their Kerama diving experience.
Gentle Currents for Effortless Exploration
The islands’ gentle natural currents guide divers along reef slopes, walls, and coral gardens, creating a smooth, relaxing dive. This allows both beginners and experienced divers to focus on the underwater scenery without tiring themselves.
Divers often enjoy spotting green and hawksbill turtles, white tip reef sharks, sea snakes, and colorful tropical fish while floating effortlessly along the reef contours. The combination of abundant marine life and scenic underwater terrain makes every dive dynamic and memorable.
