## Service `weather.get_forecast`
## Service `weather.get_forecasts`
Weather integrations which support weather forecasts expose the forecast using services. The services provided by weather entities are described below, and you can also read more about [Service Calls](/docs/scripts/service-calls/).
<div class='note'>
Some integrations may not support the `weather.get_forecast` service, but instead expose weather forecasts as a state attribute named `forecast`. This behavior is deprecated and will be removed in a future release of Home Assistant Core.
