A system for monitoring wind influences on a working machine, in particular a mobile crane or crawler crane, comprising: - at least one detection unit that is arranged on the working machine and by means of which a current wind speed can be detected; - a recording unit that is configured to receive, to store, and to transmit data of the at least one detection unit during and outside the operation of the working machine; - a controller of the working machine that is configured to determine a current working machine state; - an external processing unit that is configured to receive and to process data from the detection unit relating to the current wind speed and data from the controller directly or indirectly and in particular wirelessly; and - an output device that is configured to receive data from the external processing unit, in particular wirelessly, - wherein the controller and/or the external processing unit is/are configured to determine a limit value for a wind speed in dependence on the current working machine state; and - wherein the output device is configured to output a warning on a reaching and/or exceeding and/or impending reaching of the limit value by the current wind speed, characterized in that - the external processing unit is configured to compare the data received from the recording unit relating to the current wind speed and the data received by the controller relating to the limit value with one another, with the external processing unit further being configured to use a limit value last received by the controller in operation in a time period in which the working machine is out of operation for the comparison. - at least one detection unit that is arranged on the working machine and by means of which a current wind speed can be detected; - a recording unit that is configured to receive, to store, and to transmit data of the at least one detection unit during and outside the operation of the working machine; - a controller of the working machine that is configured to determine a current working machine state; - an external processing unit that is configured to receive and to process data from the detection unit relating to the current wind speed and data from the controller directly or indirectly and in particular wirelessly; and - an output device that is configured to receive data from the external processing unit, in particular wirelessly, - wherein the controller and/or the external processing unit is/are configured to determine a limit value for a wind speed in dependence on the current working machine state; and - wherein the output device is configured to output a warning on a reaching and/or exceeding and/or impending reaching of the limit value by the current wind speed, characterized in that - the external processing unit is configured to compare the data received from the recording unit relating to the current wind speed and the data received by the controller relating to the limit value with one another, with the external processing unit further being configured to use a limit value last received by the controller in operation in a time period in which the working machine is out of operation for the comparison.
