Weather in Monterrey changes the feel of the city because this is a place where comfort depends on more than the number on a forecast. A mild month can make metro transfers, neighborhood walks, outdoor meals, and photography feel easy.

Best Month to Visit Monterrey for Weather

January is the best month to visit Monterrey for weather in a typical year. Average daytime highs are near 68F (20C), while nights are around 40F (5C). Precipitation averages 0.5 inches, so the month is usually more comfortable than the wetter, hotter, or colder parts of the year.

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.

May is the worst month to visit Monterrey from a pure weather perspective. Average highs are around 87F (30C), and nights are near 59F (15C). The month also brings some rain, averaging about 1.6 inches, 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 May acceptable for flexible travelers, but it is not the month I would choose for the best weather in Monterrey.
