1. A method for determining a weather area for a motor vehicle comprising a sensor system and a communication interface that are signal-coupled to one another, the method comprising:
receiving data that comprise geographic information in a form of a map;
creating a grid by subdividing the received data into a plurality of mutually adjoining grid cells;
providing a measurement signal of the sensor system that is representative of a location-related local weather situation in one of the grid cells;
determining a local weather area for a respective grid cell depending on the measurement signal provided;
setting respectively one temporal counter for a respective grid cell, said temporal counter having a predetermined value depending on the measurement signal of the sensor system and being representative of a predetermined time interval during which an additional determination of the local weather area for the respective grid cell by the motor vehicle is prevented; and
resetting the respective temporal counter of the grid cell for which the measurement signal of the sensor system is provided and/or for which the local weather area is determined,
wherein the measurement signal of the sensor system comprises a weather-associated characteristic of the location-related local weather situation in one of the grid cells.
