The weather forecast for February 18 in Ciudad de Mexico and Estado de Mexico shows a notable contrast between early morning frosts and a warm afternoon expected to reach temperatures of 27 to 29 degrees Celsius. The National Meteorological Service has reported that while Northern Mexico is experiencing the effects of cold front number 35, the central region will be under the influence of an anticyclonic system, resulting in different weather patterns in the same day.

In Mexico City, temperatures will start off cool, ranging from a minimum of 10 to 12 degrees in the morning, before transitioning into warmer conditions by midday. The skies will remain clear to partly cloudy with no expected rainfall. However, residents can expect wind gusts up to 35 km/h originating from the south and southwest, which could add to the feeling of chill in the morning. This unique combination of weather conditions highlights the complexity of Mexico's climate during February, showcasing the significant variations that can occur in short time spans.

Similarly, the Estado de Mexico is seeing a division in temperatures, where mountainous regions will be subject to cold weather while the southwestern territories are likely to experience warmer conditions. This variance underscores the geographic diversity and climatic contrasts within Mexico, reflecting how different areas react to prevailing weather systems. Residents are advised to plan their day accordingly, dressing in layers to accommodate the changing temperatures throughout the day.
