You take all information available to you and make a judgement based on flying within your and the aircraft limits.
I can remember a glorious flight in a mooney to San Sebastian. Flying in perfect VFR conditions low level over the beaches I could not believe my ears when Biarritz was reporting sky obscured RVR 300 metres.
I asked for the San Sebastian weather a few miles away which was still good with fog rolling in.
Checked the fuel for a return back and was soon flying over fog banks to San Sebastian.
Literally cleared fog banks with the runway below. Full flap and landed.
Another occasion In a private jet I was told to take up a radar heading into Bournmouth.
Right on track was a nasty CB. The controller insisted there was nothing on her radar my eyes told me different.
Declined the heading!
Yes you have to take information from a number of sources ATC included and make a judgement.
That Judgement should depend on flying within your own and the aircrafts limits!
