The coldest temperature ever recorded in Argentina is widely cited as -29°C (-20.2°F) , measured in Sarmiento, Patagonia, on June 1, 1907. In recent cold waves, places like Maquinchao and Buenos Aires have also hit extreme lows, but those are not the national record.

Quick Scoop

If you mean the coldest temperature possible in Argentina , there is no fixed “absolute floor” set by nature or law. But in real-world weather history, -29°C is the benchmark most often cited for the country’s all- time cold record.

Why it matters

Argentina is huge, so the coldest readings usually come from Patagonia and other southern inland areas, where Antarctic air can drive temperatures far below freezing. That is why places like Sarmiento and Maquinchao keep showing up in record cold reports.

Recent context

A major cold spell in July 2025 brought new local lows in parts of Argentina, including Buenos Aires at -1.9°C and Maquinchao around -18°C to -19.2°C , showing how severe winter outbreaks can still get. Even so, those were regional or city records, not the all-time national record.

Answer in one line

Argentina’s coldest officially cited temperature is -29°C in Sarmiento, Patagonia, in 1907.
