On Friday, May 9, 2025, the metropolitan area of Monterrey, Nuevo León, woke up to a mostly cloudy sky and cool conditions. The minimum temperature recorded in the early hours was 18 degrees Celsius, with a thermal sensation of 17 degrees Celsius. Sunrise was around 05:58 A.M., while sunset is expected at approximately 19:16 hours, with sunlight lasting until about 19:36 hours. During the morning, temperatures will hover between 18 and 19 degrees Celsius, but a maximum of 24 degrees Celsius is anticipated, with a thermal sensation potentially reaching 25 degrees Celsius.
However, meteorologists are warning of unstable weather conditions across the state of Nuevo León. According to reports from the National Meteorological Service (SMN), very heavy to intense isolated rains are expected, accompanied by wind gusts, electrical activity, and possible hail. There is also a risk of whirlwinds or tornadoes forming in the northern part of the state. These conditions are attributed to the movement of cold front number 42, which is reinforced by a new mass of cold air interacting with the subtropical jet stream, generating winds of between 60 and 80 kilometers per hour and dust storms, particularly in the northern regions of Coahuila and Nuevo León.
As the day progresses, the probability of rain is forecasted to be around 20 percent, indicating that while the morning may see some drizzle, the afternoon could warm up with temperatures reaching 24 degrees Celsius. Despite this, the sky will remain mostly cloudy. By nightfall, temperatures are expected to drop to around 19 degrees Celsius, maintaining cool and cloudy conditions.
In light of these weather conditions, Protección Civil de Nuevo León has issued several recommendations. They advise residents to avoid unnecessary outings during storms and heavy rains, refrain from crossing flooded streets or rivers, secure loose objects that could be swept away by the wind, and disconnect electrical appliances during electrical storms to prevent short circuits. Staying informed through official channels like Protección Civil and the SMN is also crucial.
Looking ahead, the weather forecast for the upcoming days appears to improve. For Saturday, May 10, which coincides with Mother's Day, a pleasant day is expected with little to no chance of rain and temperatures ranging from 19 to 28 degrees Celsius. Sunday is projected to be sunny, with minimum temperatures of 17 degrees and maximums reaching 30 degrees, completely ruling out precipitation. The trend of rising temperatures continues into Monday, with highs potentially reaching 33 degrees Celsius, and by Tuesday, temperatures could soar to a blistering 39 degrees, particularly in the afternoon.
As residents prepare for the weekend, it’s advisable to dress in layers, opting for light clothing combined with a waterproof jacket to adapt to the fluctuating temperatures. Footwear should be water-resistant to stay dry during morning rains, and carrying a compact umbrella or waterproof hat is recommended.
In addition to weather precautions, there are various activities to enjoy in Monterrey during this time. The cool weather provides an excellent opportunity for indoor activities, such as visiting museums or cozy cafés. Alternatively, for those preferring to stay home, it’s a perfect day to catch up on reading or personal projects.
The recent weather events, including the rain that surprised Monterrey residents on Thursday, May 8, have sparked discussions about the unpredictable nature of May's climate. As people plan their activities for the weekend, they are left wondering if the weather will cooperate for outdoor events or if further rain is in store.
In summary, while the weather on Friday, May 9, 2025, is characterized by cool temperatures and a likelihood of rain, the following days promise to bring warmer and sunnier conditions, allowing residents to enjoy outdoor activities without the concern of rain. With temperatures set to rise significantly by mid-next week, it is essential for Monterrey's residents to stay prepared and vigilant about the changing weather patterns.
Finally, it’s worth noting that Monterrey has experienced significant weather variations historically, with records showing the hottest day reaching 48 degrees Celsius on April 24, 1958, and the coldest day recorded at -7.5 degrees in 1983. The average annual temperature in Mexico stands at 19 degrees Celsius, but cities like Monterrey frequently experience extreme highs, especially during summer months.
As climate change continues to affect weather patterns globally, experts warn of increasing temperatures and decreasing rainfall, which could lead to more severe droughts and flooding events in the future. This reality emphasizes the importance of preparedness and adaptability in the face of changing environmental conditions.
