Always fog in LLER but isn't in real life and also in the Metar

I know because I searched for a thread I glanced through just recently (didn’t find though), where there was always fog at an airport in India, and it turned out that the local METAR seemed to report 9km instead of 9999 for 10+km.

I think it may be this thread you are talking about, not in India but in Cuba:

Why is there always fog when flying into Cuba/MUHA Airport?

On clear sky days(As per Metar) when flying into Cuba’s airport MUHA, there is always a fog that appears when getting close to airport. This happens every time. Why is this?
