The 2026 heat wave could become one of the most intense in recent years in Nuevo León. According to the National Water Commission (Conagua), this period of extreme heat is expected to begin between July 12 and 15, with temperatures that could exceed 40 °C and even break some historical records recorded in the state.
In addition to the rise in heat, a decrease of between 40 and 60% in rainfall is expected, a scenario that could worsen drought conditions and increase the risks associated with high temperatures.
What is the heat wave, and when does it begin in Nuevo León?
A heat wave is a period that occurs every summer and typically lasts about 40 days. During this time, rainfall decreases considerably while temperatures reach some of their highest levels of the year.
For 2026, forecasts indicate that the heat wave will be particularly intense, so authorities recommend taking precautions to prevent heatstroke, dehydration, and other problems related to extreme temperatures.
Recommendations for Protecting Yourself from Extreme Heat
Experts advise staying hydrated even if you’re not thirsty, avoiding direct exposure to the sun during the hottest hours of the day, and wearing light-colored, lightweight clothing. If you exercise or engage in outdoor activities, try to do so early in the morning or in the late afternoon.
If you have pets, avoid taking them outside when the pavement is very hot, never leave them inside a car, and make sure they always have fresh water and a shaded spot.
For older adults, it is important to offer them water regularly, keep spaces well-ventilated, and watch for symptoms such as dizziness, confusion, or very hot and dry skin.
For children, the recommendation is to ensure they stay well-hydrated by drinking plain water, avoid outdoor activities during the hottest hours of the day, and never leave them inside a vehicle, even for just a few minutes.
By taking these measures, it is possible to reduce risks during the hottest season of the year and cope with the heat wave more safely.
