The invention relates to a method for operating an elevator installed in connection with a building, particularly a high rise elevator, in which method the expected rope sway is monitored using building acceleration data obtained by means of a sensor to calculate a building sway, and whereby based on the building sway and the position of an elevator car a rope sway is estimated, which rope sway is compared with a threshold value to determine excessive rope sway and to deduct operation measures for the elevator in order to counteract a determined excessive rope sway. According to the invention a succession of following steps is performed: This leads to an early detection of a possible excessive rope sway happening in the future in course of servicing elevator calls by the allocated elevator car.
