⚠ Malaria is endemic throughout Papua New Guinea below 1,800 m (5,900 ft). Begin antimalarial prophylaxis before arrival as directed by a travel medicine specialist, and use insect repellent and bed nets consistently. May's drier conditions do not eliminate mosquito-borne risk.
⚠ Highland regions above 2,000 m (6,560 ft) can see overnight temperatures drop to 10 to 12 degrees Celsius (50 to 54 degrees Fahrenheit), a sharp contrast to the coastal heat. Trekkers on the Kokoda Track and in the Highlands need layering capacity for these swings.
⚠ Residual wet-season moisture means river crossings on trekking routes may still run high in early May, in the Owen Stanley Range. Flash flooding remains possible after heavy afternoon storms. Never cross a river above knee height without guide assessment.
