Missed the cold already? The 2025-2026 cold front season is already here. According to the forecast of the National Water Commission (Conagua), 48 of these systems are expected in Mexico.
The season usually starts in September and ends in May of the following year. In a press conference it was detailed that this season we are expecting fewer cold fronts than the historical average; even between September and November temperatures are expected to be a little warmer than normal for the season, especially in the western part of the country and the northern table.
However, this does not mean that it will not be cold. In fact, the forecast indicates that “below average minimum temperatures” are expected in the Sierra Madre Occidental.

- Cover nose and mouth when leaving a warm place in order to avoid sudden temperature changes.
- Preferably do not use ovens, stoves and braziers to heat your home.
- Maintain adequate ventilation in case you use a heater or fireplace.
