In Connect for ArcGIS, data sources provide connectivity to third-party business systems. The **Open-Meteo Weather** data source allows you to current and weather forecast information for anywhere in the world.

Open-Meteo is an open-source weather API and offers free access for non-commercial use. You can learn more about [the Open-Meteo service here](https://open-meteo.com).


The Open-Meteo weather data source uses the geometry of any selected feature to fetch the weather information. For a point feature, the weather for that point location will be requested; for a polygon or polyline, the weather returned will be for the centroid of the feature.

## Data Source Configuration

The Open-Meteo weather data source configuration requires a few fields: -

- Date Format - An ISO locale code to describe the date formatting.  
For example, `en-AU` for English/Australian or `fr` for French.

## Layer Link Configuration

- Key Attribute - an attribute on the feature layer that contains a unique identifier (e.g. OBJECTID).

- Displayed Time Zone - Optional field to set the time zone to use when displaying timestamps. By default, uses the time zone of the selected map feature.
