I swim all year round in that pool and find the water to be a bit too warm right now 😃. In winter it gets down to 16°C (61F) which is bit of a challenge even for me. I do not stay there for more then a few minutes but some locals do laps all year...
Thanks.
Yes it is ocean water pool. There is a pump house at the end of the pool so the water from the ocean is constantly pumped in and it spills over the edge of the pool back into the ocean. The f stop was not higher than 5.6. I use ND filters...
