Congo in December

Dry season runs June through August and December through February — your best bet for accessible roads and clear skies. July and August offer the most reliable weather for gorilla trekking, though you'll pay peak prices. December and January provide good conditions with fewer crowds, but book accommodations early as options are limited. The rainy season from March to May turns roads into mud baths and makes some areas completely inaccessible. But here's the upside — the forest explodes with life, and you'll have places almost entirely to yourself. September through November brings unpredictable weather but reasonable prices. For gorilla permits, book at least six months ahead regardless of season.
