The 2024-2025 cold front season begins in October, with at least two expected to influence the Yucatán Peninsula in the first month.
Climatologically, the 2024-2025 winter season starts in September and ends in May of the following year. During this period, the State Coordination of Civil Protection (Procivy) predicts the influence and effects of at least 19 cold fronts on the state’s territory, some of which will be stationary.
According to projections from the National Meteorological System and statistics from the National Water Commission (Conagua), along with assessments from the State Monitoring and Alert System (SEMA) of Procivy, the normal average is 50 frontal systems affecting the national territory, of which 50 percent pass over or influence the Yucatán Peninsula.
Procivy’s outlook for the 2024-2025 winter season is to have the influence and effects of 19 frontal systems, including those that remain stationary: two cold fronts in October, three in November, three in December, four in January, three in February, two in March, one in April, and one in May.
January is considered the “peak” of the winter season, as it records the lowest temperatures and the passage of four to five cold fronts accompanied by polar or Arctic air masses.
SEMA warned that the first cold fronts sometimes interact with tropical systems or warm and humid air masses, so it is typical for each season to have squalls with strong winds and showers, electrical activity, and occasionally hail.
Given the risk or danger posed by this encounter of opposing systems, Procivy informs the state’s population of these interactions so that they take them into account and take the necessary precautions to avoid any harm to their integrity and that of their family, as well as their property, said its head Enrique Alcocer Basto.
The public official explained that these adverse weather conditions are normal during this period of the year, starting in September, as the hurricane season ends in late November.
SEMA explained that the climatic phenomenon “El Niño” causes fluctuations in ocean temperature and changes in the atmosphere, which are a fundamental part of the behavior of tropical and winter systems.
Due to the expected influence of La Niña, in September and October there would be above-average rainfall, while from November to May the range of rainfall could remain within normal due to the trend of La Niña indicating it could transition to its neutral phase.
