An autonomous vehicle (AV) can include a predictive sensor configuration system that can dynamically determine imminent lighting conditions for a sensor array of the AV as the AV travels a current route. The predictive sensor configuration system can dynamically determine one or more configurations for the sensor array to compensate for the imminent lighting conditions, and preemptively execute the one or more configurations for the sensor array as the AV travels the current route.
