Seasonal Overview
Summer (December to March)
During summer, Santiago experiences high temperatures, often reaching up to 30°C (86°F). The season is marked by clear skies and minimal rainfall, creating ideal conditions for outdoor activities. However, the intense sun necessitates precautions against UV exposure.

Environmental Challenges
Air Pollution
Santiago faces significant air pollution issues, particularly during winter months. The city’s geography, surrounded by mountains, can trap pollutants, leading to smog and health concerns. Efforts to improve air quality are ongoing, but challenges remain.
Water Scarcity
Water scarcity is another pressing issue, exacerbated by prolonged droughts and increased demand. Sustainable water management practices are crucial to address this challenge and ensure a reliable water supply for the city’s population.
Understanding Santiago’s climate and environmental challenges is essential for residents and visitors to adapt and contribute to the city’s sustainability efforts.
