Data Services

In addition to providing Canadians with up-to-date information on past, present and future weather conditions, Environment Canada offers multiple data access services to specialized users that require information at regular intervals and in an unprocessed form.

If you have further questions about these data services, please contact us to discuss your needs and how we can help.

Details regarding the conditions of usage for ATOM Feeds and WeatherLink can be found by visiting our Important Notices page.

Feeds

Users that require timely and automatic weather updates, without the hassle of constantly viewing or refreshing the "weather.gc.ca" web site, can take advantage of a convenient ATOM feed subscription. These feeds can be delivered directly to a desktop or mobile device in a news digest format. Most browsers and cell phones are already equipped with the necessary elements to support ATOM, and there are numerous feed readers available for free downloading.

If receiving timely weather information is important to you, you may want to consider a subscription to one or more of Environment Canada's weather feeds:

  • Current Condition & Forecast ATOM feed - contains the latest current conditions and 7 day forecast details for a town/city. This feed offers the following weather elements:
    • Warning/Watch events from issue time to the time it is ended;
    • Current Conditions: Hourly weather conditions, temperature, pressure, visibility, humidity, dew point, wind, air quality health index*, and wind chill/humidex (* where available); and
    • Forecast for 7 days.

    Note: ATOM feed for some locations may not have all the above weather elements.

    The Current Condition & Forecast ATOM link is located at the bottom of all Current Conditions & Forecast web pages.

  • Warning ATOM feed - will alert you when a watch or warning is in effect for a selected region. We offer two levels of Warning ATOM feeds:
    • Small geographic coverage is associated with the Current Condition & Forecast web pages, which will alert of watches/warnings in a specific community city or town. This link is located at the bottom of all Current Conditions & Forecast web pages.
    • Large geographic coverage is associated with the report page of the Public warnings which will alert of watches/warnings in a given region. This link is located at the bottom of the Warnings and Watches content section of Alerts.

  • Marine ATOM feed - consists of latest Marine weather updates as well as watches and/or warnings for an entire area including splits. This feed contains the following weather elements:
    • Marine Warning/Watch events including ice warnings from issue time to the time it is ended;
    • Forecast weather conditions includes: winds, waves, weather & visibility and outlooks for up to 5 days; and
    • The link to the Marine can be found at the bottom of the marine forecast web page.
