There are local elections in England every year so why would it affect the Welsh elections any more than usual?
Because this is a special case, and is also the first time in a long time, if not ever, that the non-metropolitan district and county councils will be elected at the same time which will have an unknow and potentially large impact on the dynamic of the elections and therefore an impact on the coverage.

A new statutory instrument allows local authorities of all kinds and sizes to hold remote meetings, to be held before 7 May 2021.
It also provides for public access to be provided through remote means including (but not limited to) video conferencing, live webcast and live interactive streaming.
Where public notices were required to be displayed outside council offices under a 1960 Act, these notices may now be published on the council website, or in the case of parish councils without websites on the district council website.
The Regulations stipulate that a document being "open to inspection" includes being published on the council website.
This has potential significance for the conduct of elections, since it establishes the validity of the internet in Local Government law. My understanding is that electoral law currently makes no reference to the internet. The only legal requirement on Returning Officers is to publish election notices at the Council offices - any publication on the internet is entirely voluntary and designed to increase elector participation. It will be a logical development, in due course, to enshrine the internet in electoral law as a means of publishing election notices.
