  2. Activate the plugin
  3. To add a forecast to your sidebar, go to Appearance, then Widgets. Click on the Wunderground widget and add it to a sidebar.

[Upgrading from 1.x] Where is the settings page?

Version 2.0 got rid of the default settings page; now shortcodes and widgets are configured individually.

[Upgrading from 1.x] My forecast looks different

Version 2.0 made lots of changes as to how the forecast is displayed. You can download the last update of the “1.x” version of the plugin here: Version

[Upgrading from 1.x] My location can no longer be found

If your location isn’t working any more, follow the steps below:

  • Go to
  • In the “Search Locations” box, type in your location
  • Click on the location when it appears in the auto-complete box
  • When the page loads, copy the URL. It will likely look like this:
  • Copy the part of the URL after the /q/. In this example, it would be zmw:00000.4.17340
  • Use that as your location in the shortcode, like this: [wunderground location="zmw:00000.4.17340" /]
  • That should work!
How do I use my own API key?

Weather Underground has generously donated free API access to users of this plugin.

If you prefer, you can define your own API key in your installation’s wp-config.php file by setting a WUNDERGROUND_API_KEY constant, like so:

define( 'WUNDERGROUND_API_KEY', 'myapikey' );

You can also override the API key using the wunderground_api_key filter, like so:

add_filter( 'wunderground_api_key', 'my_custom_wunderground_api_key' );

 * Use my own API key!
 * @return string My API key
function wunderground_api_key( $old_api_key = '' ) {
    return 'myapikey';
How do I use my own icons?

If you want to use your own icons, you would add a filter to the bottom of your theme’s functions.php file. See a list of icons you should have available. Here’s sample code:

add_filter('wp_wunderground_forecast_icon', 'use_custom_wunderground_icons', 10, 2 );

 * @return string URL to the root folder of the icon set.
function use_custom_wunderground_icons( $url_base = '', $icon_name = '' ) {
    return '';
I want to modify the forecast output. How do I do that?

Please see the “Using your own template” section on the Plugin Github page

I’m making changes to the settings, but nothing changes

The output of the widget is cached for speed. Add ?debug to the URL and it will refresh.

You can also add add_filter( 'wunderground_twig_debug' '__return_true' ); to your functions.php file to disable caching during development. Only disable caching when absolutely necessary; it will slow down your site.

Do I need a Wunderground account?

Weather Underground has been very gracious and has provided the plugin with free data – you don’t need your own account. If you want to use Wunderground data in your own application, register for a Weather Underground API account.

Confirmed with Zach Katz, since the Weather Underground API changed this plugin is no longer supported. Too bad. I think it was the only plugin for accessing Weather Underground weather station data.

Rarely works. Added in several places and I keep getting ‘location not found’ or it is blank even though it was working moments ago. The layout and design are ok.

Looks and works great. It has many customization options. I tried many other weather plugins and this was one of the few that actually worked. It regularly updates showing the current forecast with any weather alerts. Very happy with it.

  • Improved data storage, fixing issues users were having with Celsius / Fahrenheit settings and setting the number of columns in a table
  • A new cache option has been added to the shortcode. Add cache=0 or cache= to the shortcode to disable storing forecasts. Not recommended; will dramatically slow down site.
    • If you want to refresh the results, you can add ?cache=false to your URL and the forecast will be updated.
  • Added “width” option to shortcode to define table width. 100% is the default. Use width=0 or width= to disable hard-coding width in table.
  • Changed the default high/low setting to add the degree symbol.
  • Removed code whitespace when storing table for added speed
  • Added CSS classes to forecast columns based on weather conditions. This will allow you to make “Partly Cloudy” columns gray, “Sunny” blue, etc.

    • wp_wunderground_forecast_cache – How long results are cached for. Default: 6 hours.
    • wp_wunderground_forecast_icon
    • wp_wunderground_forecast_conditions
    • wp_wunderground_forecast_temp
  • Rounded column width to two digits. Instead of 16.66666667%, it’s now 16.67%

  • Added a check for PHP5 and simplexml_load_file, which are required for the plugin.
