A weather messenger is generally an indication of a future change in weather .

This is a term used almost exclusively in everyday language. Clouds , for example , are good weather messengers , but many are also familiar with the flight of swallows as a reliable weather messenger. If they fly high, it is assumed that the weather will improve. If they fly low, it is concluded that it will get worse.

Such weather indicators, such as the sunset , are not meteorological criteria for predicting a change in weather and are also often based on purely empirically derived and only very regionally valid peasant rules , which is why their use should generally be avoided.

Direct indications of a weather change are based on the weather observation , i.e. the temporal course of temperature and air pressure in combination with the observation of the cloud development, from which a local weather forecast can be created with comparatively little meteorological knowledge . These are only associated with a small amount of measurement and work, but in return they achieve a significantly higher level of reliability than weather forecasts based on indirect observations - the weather messenger - which is why they are usually superior to them.
