Mexico's first heat wave of the year is forecasted to affect four states this week, with temperatures ranging from 30 to 45 degrees Celsius. Despite still being in the winter season, the National Water Commission's Meteorological Service warns that this heat wave, coupled with a middle-atmosphere anti-cyclone, will lead to a low likelihood of rainfall and warm to hot afternoon weather. Many states will experience high temperatures at least until Thursday, February 19, while higher-altitude areas will continue to see frost in the mornings due to the passage of cold front 35.

The specific states likely to experience the most extreme temperatures include Michoacán, Guerrero, Oaxaca, and Chiapas, where maximum temperatures are expected to reach between 40 and 45 degrees Celsius. Other regions, such as Coahuila, Nuevo León, and Tamaulipas, will see temperatures ranging from 35 to 40 degrees, suggesting a widespread effect across significant areas of the country. The unusual heat during winter raises concerns about climate patterns and the implications for agriculture and daily life.

This early heat wave poses multiple implications for the region, including potential impacts on water resources, agriculture, and public health. As the country is still within the winter season, an early onset of heat can strain existing resources and increase the probability of drought conditions in the coming months. Authorities and residents are urged to stay informed and take precautions during this unprecedented weather event, highlighting the importance of preparedness as climate extremes become more common.
