Rainy day

Today it’s rainy here in Okinawa. But its not that cold underwater. Sea is calm. We went to blue cave this morning to take some pictures. Tomito is  making short videos using those pictures. Even though it was raining  a bit, the pictures are very good.

Sunny day

Hi everyone. Today the weather in Okinawa is like mid summer. After few cloudy days the sun is out. Sea condition is also perfect to go for a dive or snorkeling. I just came from a dive at blue cave and the visibility is like 20 meters. Water temperature is also around 26.
