Air Quality Data

Air Quality data is returned in the Forecast API, History API and Realtime API response. Depending upon your subscription plan we provide historical (from 1st March 2021 onwards), current and 3 day air quality data for the given location in json and xml.

It provides air quality index (see below) data on major pollutant gases like Carbon monoxide (CO), Ozone (O3), Nitrogen dioxide (NO2), Sulphur dioxide (SO2), PM 2.5 and PM 10.

By default air quality data is not returned. To get air quality data back in the response from Forecast API, History API and Realtime API, pass the parameter aqi=yes.

Field Data Type Description
co float Carbon Monoxide (μg/m3)
o3 float Ozone (μg/m3)
no2 float Nitrogen dioxide (μg/m3)
so2 float Sulphur dioxide (μg/m3)
pm2_5 float PM2.5 (μg/m3)
pm10 float PM10 (μg/m3)

Bulk Request

If you are on Pro+, Business or Enterprise plan then you may use our bulk weather option to send multiple locations to get weather for all the locations sent in a single request.

Each location sent in bulk operation is counted as 1 call. It works for all the API methods except Search API.

For bulk you need to pass in the querysting q=bulk and then pass a json body as POST method with utf-8 encoding. All the the other request parameters will be passed as query as usual.

Thanks to Dzebo Elvis for pointing out that the POST method should be used and not GET.

Json format for sending multiple locations in the POST body.

                            {
    "locations": [
        {
            "q": "53,-0.12",
            "custom_id": "my-id-1"
        },
        {
            "q": "London",
            "custom_id": "any-internal-id"
        },
        {
            "q": "90201",
            "custom_id": "us-zipcode-id-765"
        }
    ]
}
                            
                        

Json format explanation

Parameter Description
q (required) You may pass lat and lon, US zipcode, UK postcode, city name, IP, etc.
custom_id (optional) We will return this custom_id back in the response for you to use it at your end. It is for better management at your end. We don't use this id for anything.

Weather Icons and Codes

In the JSON response we return a condition:code which is a code for describing weather. For example clear, sunny, etc.


You may retrieve the whole condition list as JSON to implement different weather icons or apply other logic to your application. It also includes multi-language translations of weather condition text.


Multilingual Condition list URL: https://www.weatherapi.com/docs/conditions.json


English Condition list URL (CSV): https://www.weatherapi.com/docs/weather_conditions.csv


English Condition list URL (JSON): https://www.weatherapi.com/docs/weather_conditions.json


English Condition list URL (XML): https://www.weatherapi.com/docs/weather_conditions.xml


Please download the list and use it offline instead of directly linking into your application.
