What you might see
Too few open records near this site to list its animals. Ask a dive centre what you are likely to see.
This week: visibility about 6 m, clearer than usual (satellite plankton reading, 24 Oct). Estimated from the month's typical visibility and this week's satellite chlorophyll against the site's normal; heavy rain before a dive can still muddy it.
The current and the life no free forecast gives. Ask a dive centre before you book.
