Pointe‑Noire & Mayombe Coast

Showers taper but remain frequent in May, and the Atlantic keeps a humid, muggy blanket over the region with temperatures still commonly in the upper 20s°C. Coastal roads can develop potholes and smaller villages may become temporarily cut off; dive operators sometimes reduce schedules because of reduced visibility. A flexible schedule and waterproof packing remain essential for travelers planning beach or forest excursions.

Niari Plateau & Southern Highlands

May keeps the plateau wet and humid as the rainy season continues; daytime temperatures remain warm but cloud cover moderates the heat. Wildlife viewing in thicker woodland becomes more difficult because animals disperse with abundant water, yet birding is rewarding as migratory and resident species are active. Travel times lengthen on rural roads, so keep a flexible schedule and waterproof bags for gear.

Brazzaville, Pool & Congo River Lowlands

May’s rains remain frequent but are often interspersed with bright, warm breaks; the river continues to rise and wetlands become more pronounced around the Pool. Boat trips to riverine villages provide striking watery scenery but be ready for rain interruptions and muddy landings. Practical gear - quick‑dry clothing, waterproof footwear and protective cases for electronics - will make exploring easier.

Odza‎la‑Kokoua & Sangha‑Northwest Parks

May continues very wet and some park roads can be significantly slowed by heavy rainfall; remote sectors may require longer boat transfers or temporary suspension of activities. The wet forest is dramatic and verdant, but for reliable game and primate tracking the coming drier months are preferable. Ensure you pack rainproof outerwear and confirm lodge transport arrangements well in advance.

Likouala Floodplains & Northern Basin

May keeps the basin saturated and rivers high; canoe travel is reliable but expect slow progress and strong currents in tributaries after heavy rains. Wildlife viewing from boats can be excellent as animals concentrate in remaining high ground, but overland trekking is still mostly impractical. Waterproof your luggage and plan for flexible boat schedules when exploring the floodplain.
