|Dive No. 1461/1462, Monday July 25th, Big Munsom Bay, Visibility 3-6 meters, Air 32 C, Water 24 - 18C
We were diving with our guests at the bay of Big Munsom. The swell was 1.5 meters high and we expected to get more wind in the afternoon so we decided not go boat diving which turned out to be a good idea.
Since typhoon Haitang has brought us some high seas last week the visibility has been very poor. Water temperature near the surface is 24 degrees and the warm water has caused a rapid growth of plankton which has turned the water into a greenish soup. Visibility in these upper layers is a little as 3 meters.
Between 12 and 18 meters of depth there is a thermocline which devides the warm water from the cold. Below the thermocline the water temperature suddenly drops to 18 degrees and the water is considerably clearer with a visibility of 6 - 10 meters. Unfortunately there is not much sunlight coming through the green plankton soup. So colors do not come out that well.
These conditions might continue for a few more days but I hope it changes soon.
Best wishes to everybody and safe diving!
