The boat was full house, but the weather was… 🙁

Last year on October 11, ground temperature was 32C and water temperature was 29C – feels as if winter is running toward us! Hope the warm weather will return!


As the swells were big, we stayed around Osaki and Nagura area for three dives. I prefer warm water, but cold water is good for corals… (^^;


There was a pair of Filament-finned prawn-goby 🙂


Longfin batfish with orange outline  is a juvenile one.


When will we see the sun…?
