Puerto Montt, Chile, with 19.9°C tied its Record of August Highest Temperature in History

Chile experienced a notable heat anomaly in August 2025, with Puerto Montt reaching 19.9°C, tying its all-time record for the highest August temperature in history. For a city located in the southern mid-latitudes, where August is normally cool and transitional toward winter, this temperature is exceptionally warm.

This event highlights the continuing trend of unusual heat extremes across the Southern Hemisphere. Even areas typically considered temperate and mild are now experiencing record-shattering warmth, signaling broader climate anomalies affecting Chile and southern South America.

Tying the August high-temperature record at 19.9°C places Puerto Montt among a growing number of locations globally where monthly and all-time records are being matched or broken in 2025. While not as extreme as the 41–42°C events in Paraguay or Lillooet, this event is still significant for the local climate record, particularly given the southern hemisphere winter approaching.

In summary, Puerto Montt’s 19.9°C marks a historic tied-record for the warmest August day, emphasizing that unseasonable warmth is affecting diverse regions worldwide, from tropical capitals to temperate southern cities.
