If you are logged into your account on wunderground.com, go to your list of weather stations here:
Click the settings gear next to your station name and see the option to "Edit" or "Delete".
The "Delete" option doesn't work once a station has uploaded data. We can only delete a station if we've never received data for it.
But if you stop uploading data for a station, it will be removed from location searches and maps.
If you have additional questions, please email firstname.lastname@example.org.
