We tried the Penrhos yesterday, 5 miles off shore from Colywn Bay near the bird filters... Viz around 2/3m... Plankton bloom very much in full swing and no sign of the jellies as of yet... If it holds to form, it'll start to improve mid/late June...
Vis is a good 8m around Abersoch, St Tudwal's etc.
If you go south from Anglesey the vis is pretty good, around 6-8m below 30m, but there's a lot of snot in the water till you get to depth, and it's a bit dark.
