Intense Cold Leaves San Juan Bautista Covered in Frost at Dawn

The capital of Misiones province, San Juan Bautista, awoke on Tuesday, June 23, 2026, under a blanket of frost. Temperatures plummeted to 6 degrees Celsius, causing a layer of ice to form on pastures, crops, and green spaces, as predicted by the Directorate of Meteorology.

Despite heavy rains recorded since Monday morning, which kept soil humidity high, the low temperatures overnight facilitated the formation of frost. This phenomenon occurred as accumulated dew crystallized on surfaces, creating a characteristic white coating on various grassy areas. The temperature reached its lowest point around 7:00 AM.

Producers pointed out that the abundant rainfall recorded during the past week and yesterday have not yet generated significant damage to crops.

Agricultural producers noted that the abundant rainfall from the previous week and Monday had not yet caused significant damage to their crops. However, they cautioned that a prolonged period of low temperatures could negatively impact plants currently in their growth stages, as many species are sensitive to intense cold during early development.

Some small-scale farmers, anticipating frost warnings for the week and lacking protective measures like shade cloths, resorted to covering their horticultural crops with bags to shield them from the cold. This preventive measure aims to avoid damage to vulnerable plants. Meanwhile, health centers in the department have reported an increase in consultations for respiratory illnesses, particularly among children and the elderly, who are most susceptible to sudden temperature changes. The Departmental Directorate of Education in Misiones has consequently adjusted school entry times and made school uniforms optional to allow students to wear warmer clothing.

Professionals in health warn that low temperatures favor the appearance of respiratory diseases such as colds, flu, bronchitis, and pneumonia.
