Techniques are disclosed for systems and methods to provide water temperature and sonar imagery for users of mobile structures, including watercraft. A water temperature display system includes a water temperature sensor and a logic device configured to communicate with the water temperature sensor. The water temperature sensor is configured to measure a temperature of or near a surface of a body of water. The logic device is configured to render water temperatures according to a three dimensional view of an area about a mobile structure. Subsequent user input, water temperatures, and/or the rendered view may be used to adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.
