A Little Swell Has Started to Reach Kushimoto
It was a busy day of weather, with rain, sunshine, and clouds changing throughout the day.
The swell from the remnants of Typhoon No. 24 has started to reach Kushimoto.
However, thanks to Cape Shionomisaki, the dive sites inside the bay were still diveable.
Some of our originally booked guests had to cancel, so in the end, we enjoyed two days of one-on-one fun diving with our guest.
The visibility was around 10 meters, and the water temperature was 27°C.
Before the typhoon, both the visibility and water temperature had been excellent, so we really hope the effects of the storm do not last too long.
Since today’s guest had also dived with us yesterday, we started the day at a different dive site.
We enjoyed everything from wide-angle scenes to macro subjects!
It was the guest’s first time diving in Kushimoto, so of course we had to introduce one of Kushimoto’s representative fish: Stripy Butterfly Fish.
For divers who regularly dive in Kushimoto, seeing them may feel like an everyday sight.
But when you stop and take another look, their large schools are one of the underwater scenes that really feel unique to Kushimoto.
This year, we have been seeing a lot of Silver striped round herrings.
On our second dive today, a huge school of Silver striped round herrings welcomed us underwater.
Rainbow runner and Bonito were swimming around the school, creating a powerful and exciting scene.
When the school gathers tightly together, the whole scene becomes even more impressive.
Silver striped round herrings usually become more abundant as we move toward autumn, so we are really looking forward to the coming weeks.
For macro diving, we introduced several different nudibranchs.
This summer, we have been seeing many members of the Siphopteron group.
Among them, we found a relatively rare Siphopteron tigrinum today.
We hardly saw them at all last year, but this was already our third encounter this year.
If they continue appearing as we move into autumn, it will be very interesting to see how the season develops.
We are already looking forward to this autumn and winter!
We also found Trapania palmula today.
Once you understand what they feed on, they can become a little easier to find.
This individual was around 1 cm in size, making it relatively easy to observe.
It looks slightly similar to Trapania euryeia, but it is a different species.
Identifying nudibranchs can sometimes require checking very small details, so we always try to pay close attention when taking identification photos.
We also had a nice surprise with Harlequin Shrimp.
It had been difficult to see recently, but today it came out into the open.
Because it was cloudy and a little darker underwater, some creatures were more active outside their hiding places.
On bright days, some animals stay hidden in cracks and shadows, while rainy or cloudy conditions can sometimes give us a better chance to see them.
So rainy days are not always a bad thing.
There are underwater scenes that we can enjoy precisely because the weather is not perfect.
Since the beginning of September, we have been dealing with typhoons and changing weather conditions.
However, except for last Sunday, we have still been able to dive so far.
Silver Week is coming in about two weeks, so we really hope the typhoons will give us a break soon.
This week, we have started receiving more inquiries for diving in October, as well as dry suit training in November.
Fun diving in September is of course still available, but please also check our free dry suit rental campaign from November through December.
If you are planning fun diving in Kushimoto this autumn or winter, please feel free to contact us.
Tomorrow, we are scheduled to conduct an AOW course.
The boats will be closed, so we will focus on the sections that can safely be completed from the beach.
See you again soon!
