Questions & Answers about Wieczorem patrzę na płonące ognisko.

Why is it wieczorem and not w wieczór?

Polish usually uses the instrumental case (without a preposition) to talk about when something happens:

• wieczorem – in the evening
• rano / rankiem – in the morning
• nocą – at night
• zimą – in (the) winter

Wieczorem is the instrumental form of wieczór and functions almost like an adverb: “in the evening”.

Using w wieczór is not natural in modern Polish in this meaning. You might see wieczór with w in some fixed phrases like w ten wieczór (“this evening”) or w każdy wieczór, but for a simple “in the evening” you say wieczorem.
