Yes, but conditions can vary wildly in a control zone area. Particularly
around bodies of water.


It doesn't matter. A SVFR clearance is issued on the basis of weather
conditions reported at the airport. If the weather observation site is
enveloped in fog while the rest of the surface area is CAVU, then fixed-wing
SVFR is not available.



So a controller would issue an SVFR clearance even if the field is below
IFR
minimums?


Possibly. If the available SIAPs all have minimums greater than one mile
visibility. There is no direct connection between SVFR and IFR minimums.
