Change Default Weather Location on Edge Home Page

I have Win 10 V.1607. The default weather location on the Edge Home Page is Sidmouth, Devon. I do not live anywhere near there so I don't know how this has happened. If I go to edit on the weather app and change manually to my location and save it will change but if I close Edge and re-open it reverts to Sidmouth. If I edit and change to Always detect my location and save nothing happens. How can I set the default to my home town please? I have a desktop so I'm not going anywhere.

Thank you Kari. No I refer to the weather card that appears in the top right hand corner of the Edge Home Page, just below the settings icon. See attached.

I can change the location but when I save, close Edge and re-open the card defaults to Sidmouth again. I do not live in Sidmouth! There are solutions to this problem on the net but none work for me. The funny thing is the default weather location in the Start Menu Weather App works fine.

Yes I have done that and the weather card still defaults to Sidmouth.

My settings are not displaying in the same way, and the page has defaulted to Sidmouth. I despair. See attached.

I don't have a Microsoft Account. I didn't know that I had to have one to enable my location to be established.

I am reluctant to open a Microsoft Account because I have heard of privacy issues. Apart from that I do not need to sync with other devices as my desktop is the only Win 10 hardware that I have. I have also read somewhere that signing on to MSN does not resolve the default issue.

I am wondering what the permission is that I require for the Edge location in settings. (Sites still need permission) See attached.
