It’s ideal if your writing is trying to do two for the price of one. If your description both conveys the surroundings/place and reflects the viewpoint character’s mood, you’ve got a better chance of keeping the description-skippers engaged while saying what you need to convey.
No one wants to read a paragraph of description so slide it in other spots or give it strong vibes to set mood and tell you how it makes the character feel
pathetic fallacy—loading your description with your character’s feelings
