A collision risk calculation method for a computer to execute a process includes, calculating, by using track data of each of a first vessel and a second vessel, a risk value related to a collision between the first vessel and the second vessel at each time point by a certain method; specifying a time range before the risk value becomes a maximum risk value; extracting, from the track data, an action pattern of one or both of the first vessel and the second vessel in the time range; calculating a degree of the action pattern of one or both of the first vessel and the second vessel on the basis of the action pattern; and correcting the risk value based on the degree of the action pattern and a weight set for each action pattern.
