This Matomo plugin allows you to collect weather data on your visitors. This data allows you to have a more in-depth analysis of your data by allowing you to correlate external actions to the behavior of your users.

View and download this plugin for a specific Matomo version:

1- Install the plugin from the marketplace or via GitHub

Install this plugin from the Marketplace as super user or download the plugin and install it on your server from FTP in the /plugins folder.

Upon activation, this plugin will automatically update the structure of your database's log.visit table by adding 11 new columns prefixed weather_ for the new dimensions.

2 - Fetch data on your website

This code allows you to retrieve weather data from WeatherAPI and send it to your Matomo instance in Weather reports. Because you only need to retrieve data once per visit, this code has a sessionStorage variable to avoid multiple requests. The sessionStorage is purged each time the browser is closed.

You'll need to generate your own API key (Free plan is up to 1 Million calls per month). Replace XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX with your API Key and adjust your language if necessary.

2 - 1 With Matomo Tag Manager (Recommended)

Use the Weather custom Tag in Matomo Tag Manager (in the Openmost section)

Set your API Key and publish a new version of your container.

That's all !

2 - 2 OR with Matomo classic code (Only if you don't use Matomo Tag Manager)

Implement the _paq.push(['WeatherReports.setWeather']) method on your website using the following snippet:

<!-- Openmost WeatherReports code for Matomo -->
    async function fetchWeatherData() {

        // Fill with your credentials
        const lang = "en"; // Available lang code here

        if (!sessionStorage.getItem("matomoWeather")) {
            // Get visitor IP address
            const ipapiResponse = await fetch("");
            const ipapiData = await ipapiResponse.json();

            if (ipapiData.ip) {
                // Fetch Weather data
                const response = await fetch(`${apiKey}&q=${ipapiData.ip}&aqi=no&lang=${lang}`)
                const data = await response.json();
                const weather = data.current;

                // Send data to Matomo instance
          ,            // Cloud
                    weather.condition.text,   // Condition
                    weather.feelslike_c,      // Temperature in Celsius (for Fahrenheit, use: weather.feelslike_f)
                    weather.humidity,         // Humidity
                    weather.precip_mm,        // Precipitation in millimeters (for inches, use: weather.precip_in)
                    weather.pressure_mb,      // Pressure in millibars (for inches, use: weather.pressure_in)
                    weather.temp_c,           // Temperature in Celsius (for Fahrenheit, use: weather.temp_f)
                    weather.uv,               // Uv
                    weather.vis_km,           // Visibility in kilometers (for miles, use: weather.vis_miles)
                    weather.wind_dir,         // WindDirection
                    weather.wind_kph,         // WindSpeed in Kilometers/h (for miles/h, use: weather.wind_mph)

                sessionStorage.setItem("matomoWeather", JSON.stringify(weather));

<!-- End Openmost WeatherReports code for Matomo -->

3 - Enjoy new reports and features

Now that the plugin is correctly configured, you will find the different reports in the "Weather" section of the Matomo "Visitors" menu.

These different reports support Matomo's automatic archiving CRON for better performance (recommended)

New dimensions with segments and API methods:

| Dimension name   | Type   | Segment name           | API method                        | Tracking HTTP API parameter |
| Condition        | string | weatherCondition       | WeatherReports.getCondition       | weather_condition           |
| Cloud            | int    | weatherCloud           | WeatherReports.getCloud           | weather_cloud               |
| Temperature      | float  | weatherTemperature     | WeatherReports.getTemperature     | weather_temperature         |
| Felt temperature | float  | weatherFeltTemperature | WeatherReports.getFeltTemperature | weather_felt_temperature    |
| Pressure         | int    | weatherPressure        | WeatherReports.getPressure        | weather_pressure            |
| Precipitation    | float  | weatherPrecipitation   | WeatherReports.getPrecipitation   | weather_precipitation       |
| Humidity         | int    | weatherHumidity        | WeatherReports.getHumidity        | weather_humidity            |
| Uv               | float  | weatherUv              | WeatherReports.getUv              | weather_uv                  |
| Visibility       | int    | weatherVisibility      | WeatherReports.getVisibility      | weather_visibility          |
| Wind direction   | string | weatherWindDirection   | WeatherReports.getWindDirection   | weather_wind_direction      |
| Wind speed       | float  | weatherWindSpeed       | WeatherReports.getWindSpeed       | weather_wind_speed          |

Enjoy !

This is an example of WeatherAPI response:
