Antarctica's Summer Temperatures: Still Very Cold, But the "Warmest" Time

Antarctic summer (December–February) is the warmest season, but "warm" is relative—it remains fiercely cold by any temperate standard.

Typical Summer Temperatures

Key Points

• Melting occurs only on the Peninsula and coastal fringes, briefly.
• 24-hour daylight drives the slight warming.
• Wind chill makes it feel much colder; katabatic winds are fierce.
• Winter (Jun–Aug) plunges to −60°C (coast) and −80°C (interior).

Climate Change Signal

The Peninsula is one of the fastest-warming places on Earth (+3°C since 1950), causing ice shelf collapse. Interior trends are more complex but show slight warming.

Summer in Antarctica is a brief window of "less extreme" cold enabling field science—not warmth.
