Santiago experienced its coldest morning of the year on March 23, 2026, with forecasts of frosts and low temperatures [1, 2].

This sudden drop in temperature affects the central zone of the capital, signaling a sharp shift in weather patterns for the region. Such extremes can impact local agriculture, and public health in the metropolitan area.

Meteorologist Iván Torres said the morning was the coldest recorded so far this year in the capital [1]. The temperature drop is attributed to the passage of frontal systems, which pushed a mass of cold air into the region and generated the morning frosts [2].

Forecasts indicate that maximum temperatures will remain below 30°C [2]. This cooling trend follows the movement of these weather systems across the central zone, creating a stark contrast to typical seasonal expectations.

While other regions in South America have also reported record lows, the conditions in Santiago were driven by specific frontal movements. The combination of the cold air mass and the timing of the front resulted in the specific frost patterns observed throughout the city [1, 2].

The occurrence of the year's coldest morning in late March suggests an atypical shift in the seasonal transition for Santiago. When frontal systems drive sudden frosts and keep maximum temperatures below 30°C, it indicates a volatile atmospheric pattern that can disrupt regional climate norms and affect the timing of the spring transition.
