Does It Snow in New Guinea? Only on the Highest Peaks (Above 4,500 m)

Snow is extremely rare in New Guinea. The island is tropical; most areas never see frost.

Exception: The Sudirman Range (Papua, Indonesia) includes Puncak Jaya (Carstensz Pyramid) at 4,884 m (16,024 ft)—the highest island peak on Earth. Its summit glaciers (retreating rapidly) receive occasional snowfall. Nearby Ngga Pulu (4,862 m) and Puncak Mandala (4,760 m) may also get snow.

Conditions: Only above ~4,500 m (14,800 ft). Even there, snow is transient—equatorial sun melts it fast. No ski resorts, no permanent snowfields below 4,700 m.

Rest of island: Lowlands: 27–32°C, humid. Highlands (1,500–3,000 m): 15–22°C day, 5–10°C night—frost possible, snow virtually never.

Climate change: Puncak Jaya's glaciers lost >80% area since 1930s; may vanish by 2030.
