Weather variability in central and southern Chile

Overview

Meteorological reports indicate diverse weather patterns across several Chilean regions in late October 2026.

In the Valparaíso region, clear skies and moderate winds were expected on October 22, with temperatures between 14 and 19°C and a high UV index. However, a high-altitude trough is forecasted to bring atmospheric instability to Valparaíso, the Metropolitana, O'Higgins, Maule, Ñuble, and Biobío regions on Monday, October 26. This phenomenon is expected to trigger rain, potential hail, and electrical storms, particularly in valley, precordillera, and cordillera sectors. In the Biobío region, Senapred reported a decrease in rainfall intensity for October 23, with light precipitation in coastal areas and up to 5 cm of snow in high mountains, though risks of storms and hail persisted.

In Rancagua, heavy precipitation was forecasted with a 100% probability of rain. For October 26, rainfall estimates for the area include approximately 10 mm.

Conversely, the Coquimbo Region experienced higher than usual temperatures. In the Elqui and Limarí provinces, highs were expected to reach 30°C in areas such as Vicuña, Punitaqui, and Monte Patria. Authorities warned that these elevated temperatures could trigger snowmelt in lower altitude mountain sectors, potentially increasing river flows and activating ravines. Weather conditions are expected to improve progressively starting Tuesday, October 27, with warmer temperatures following.
