Weather in Oaxaca changes the feel of the city because this is a place where comfort depends on more than the number on a forecast.

What makes January stand out is balance. It is not necessarily perfect every day, but it usually gives travelers the best combination of outdoor comfort, manageable weather risk, and enough flexibility for a first-time trip. If hotel prices or crowds rise during this period, that popularity is at least partly weather-driven.

Rain is the main problem. The month is not impossible, but showers and damp conditions can interrupt outdoor plans and make transit transfers less pleasant.
