In some places the conditions are consistently better farther offshore. For 
example here in North Carolina (USA) warm, clear Gulf Stream waters run off our 
coast and move farther offshore in the winter.

Even in summer the vis 12 miles out tends to be in the 60 foot range while it 
may be 100+ feet 30 to 40 miles out.

Right now the water temp 12 miles out is in the low 60's (F) and is running 
about 77 (F) 100 miles out.

So in our case both vis an water temps usually improve the farther you go out.
