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

Best Month to Visit Chillán for Weather
April is the best month to visit Chillán for weather in a typical year. Average daytime highs are near 73F (23C), while nights are around 48F (9C). Precipitation averages 1.9 inches, so the month is usually more comfortable than the wetter, hotter, or colder parts of the year.
What makes April 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.
Worst Month to Visit Chillán for Weather
January is the worst month to visit Chillán from a pure weather perspective. Average highs are around 88F (31C), and nights are near 56F (13C). The month also brings dry weather, with only about 0.4 inches of rain, which can make long outdoor days less comfortable.
The issue is not one dramatic hazard but the overall comfort level. The month is simply less easy than the better parts of the year. Lower hotel prices or fewer visitors can make January acceptable for flexible travelers, but it is not the month I would choose for the best weather in Chillán.
