How to predict water visablity

Hi
I love the odd spot of snorkling around rocky beaches and I am interested in doing it more. However water visability always seems to be a lottery. If it is poor I dont enjoy snorkling much. How does one predict when there will be good water visability in the sea? Is it based on tides and wind speed?

What part of the coast are you asking about? Viz can be a hyper local thing....

Generally rain is bad, runoff from the land worse again. But a few km from a closed beach can be fine if you can get away from it.

Settled conditions for a few days are ideal, but then extended periods of sun and calm breeds algae eventually and you can have that green plankton bloom...

If you get to know an area (visit regularly) you can learn how it reacts to different conditions (rainfall, sunshine, coastal winds etc) , after a bit of time (a year or two), you might get a better idea of what the visibility will be like .

South east. Thanks a lot. I guess I should find rocky beaches with less streams near
