Santiago is expected to reach a maximum temperature of 21°C [2] on Wednesday, May 20, 2026.

The shift in weather reflects seasonal transitions in the central zone of Chile. This cooling trend follows a warmer period in the region, impacting daily activity and energy needs for residents in the capital.

TVN Chile's TV Tiempo said the city will experience high cloud cover during the morning hours [2]. This atmospheric condition is part of a broader pattern of seasonal climate changes that are currently affecting the central region of the country.

The projected high of 21°C [2] represents a decrease from the previous day. On Tuesday, Santiago reached a maximum temperature of 24°C [1]. This drop of three degrees indicates a move toward more typical autumn conditions for the area.

Meteorologists at TV Tiempo said the high cloud cover is expected to persist through the early part of the day [2]. While the morning may appear overcast, the temperature is still expected to climb to the forecasted peak before the evening cooldown begins.

Local residents are advised to monitor these fluctuations as the region enters a period of increased cloudiness. The transition from the 24°C [1] peak seen earlier this week to the current 21°C [2] forecast highlights the variability of the current seasonal cycle in the central zone.

The slight decrease in temperature and increase in cloud cover indicate a stabilization of seasonal norms in central Chile. This shift from the previous 24°C peak suggests the region is moving away from unseasonably warm spikes and returning to standard late-autumn weather patterns.
