In Monterrey, precipitation falls rather scarcely throughout the year, which corresponds to its semi-arid climate. Even in months with the highest number of rainy days, the total amount of moisture remains low, indicating mainly light rains rather than intense downpours.

The highest probability of encountering precipitation falls on the period from April to September. May stands out with the largest number of days with precipitation – on average 14 days, however, the total amount of moisture is only 2 mm, which suggests frequent but very light rains or drizzle. September is the month with the highest recorded average rainfall – 4 mm, which falls over approximately 13 days. In April, an increased frequency of rainy days is also observed, around 12. Thus, there is no distinct season of torrential rains in Monterrey; rather, it is a period with more frequent but insignificant precipitation.

The driest period in Monterrey can be considered the interval from late autumn to early spring. February demonstrates the absolute minimum both in rainfall amount (1 mm) and in the number of rainy days (only 4 days). January, March, August, and December are also characterized by minimal rainfall (1 mm each), while the number of rainy days in these months ranges from 6 to 8.

Snowfall is uncharacteristic for Monterrey, and all precipitation falls predominantly in the form of rain. Given the low volumes of precipitation even on the "wettest" days, rains tend to be light and short-lived. This means that prolonged downpours are unlikely, and for most of the time, the weather remains favorable for outdoor activities and excursions.

When planning a trip to Monterrey, it is important to consider its semi-arid climate with hot summers and mild winters, as well as low rainfall throughout the year. The basis of your wardrobe should be light and breathable clothing, especially if you are traveling from May to September, when daytime temperatures often exceed 30°C. T-shirts, shorts, skirts, and light trousers made of natural fabrics will be most appropriate. Don't forget sunscreen with high SPF, sunglasses, and headwear (a hat or cap) for protection against the intense sun. Comfortable walking shoes are a must, as you will surely want to explore the city on foot.

Despite the fact that Monterrey is not famous for heavy rains, some months, such as May (14 days with precipitation), September (13 days), and April (12 days), can bring short-term precipitation, albeit in small amounts (1-4 mm). Therefore, a light folding umbrella or a compact waterproof windbreaker may prove useful without taking up much space in your luggage. In the winter months (December-February), average temperatures hover around 14-16°C, and night temperatures can drop to 8-10°C. At this time, a light jacket, sweater, or fleece will come in handy, especially for evening walks. The principle of layering in clothing will be relevant year-round due to noticeable daily temperature fluctuations, allowing you to feel comfortable both during the day and in the evening.

Additionally, it is worth thinking about items such as a reusable water bottle to always have a drink with you and reduce plastic use. If you plan to visit more formal places or restaurants, take one or two dressier outfits with you. Given the dry air, especially during periods with minimal rainfall, moisturizing cream for skin and lip balm may also come in handy. In general, your luggage for Monterrey should be oriented towards warm weather, with the possibility of warming up on cool evenings or during the winter period.
