Prior to the approach the ASOS was reporting 2 SM and fog. We were 40 miles out from the IAF and could see ZZZ. The visibility looked clear and no fog in the area. Center cleared us the approach 25 mile outs from the IAF and cleared us to change to advisory. I hesitated on calling the visual because of my experience with fog. After determining that there was no fog and it was clear and 10 SM visibility. We tried to contact Center to call for the visual approach; but were unable to reach Center due to a NOTAM that ground comm was out. After we landed my First Officer said that ASOS was reporting a 1/4 mile and fog; which was inaccurate. It was clear and with a visibility greater that 10 SM. I was informed by the ground crew that this has been an ongoing problem with inaccurate weather. ASOS needs to be relocated or repaired.
CRJ200 Captain reported ASOS was broadcasting inaccurate weather.
