Conagua Forecasts Active 2026–27 Cold‑Front Season With 56 Systems

Overview

• Conagua issued an official seasonal forecast on Tuesday that projects 56 cold fronts in Mexico from September 2026 through May 2027, above the 1990–2020 average of 50.
• The first front is expected between September 22 and 23 to enter from the northern border and will affect northern states first, with the SMN warning gusts up to about 70 km/h in places such as Tamaulipas.
• The forecast says the coldest impacts—near 0–5°C—will be limited mostly to highland and mountain zones in states including Chihuahua, Durango, Estado de México, Hidalgo, Michoacán, Puebla and Tlaxcala.
• Conagua’s monthly breakdown shows the season peaks in November–January, with 32 of the 56 fronts expected in that window and December the busiest month, directing preparedness priorities for coastal and northern communities.
• Cenapred and meteorological agencies note fronts form when a cold dense air mass undercuts warm air, typically last 3–7 days, and can cause Norte events, high waves, storms and localized snow, so authorities urge people to follow official updates and local protection measures.
