A disturbance estimation apparatus including a navigation data receiver, a thrust data receiver, and processing circuitry is provided. The navigation data receiver acquires navigation data including an actual position and time of the ship on a water surface. The thrust data receiver receives thrust data indicating a magnitude and a direction of a thrust force of the ship. The processing circuitry estimates a predicted position of the ship at a future point in time and a predicted arrival time of the ship to reach the predicted position by inputting the navigation data and the thrust data into a first trained model, and determines disturbance data including a drift direction and drift speed of the ship drifted by an external force based on a difference between the predicted position estimated by the first trained model and the actual position of the ship at the predicted arrival time.
