Temp gauge on dash cluster, the needle goes past the bottom line below the C on 2001 Ford Explorer Sport Trac

overnight the needle goes about 1/4 inch past the line below the C on the gauge. While running the vehicle all day it never goes past 1/4 inch above the C. Would this be a gauge issue or could it be a bad sensor?
