High rainfall across the country; travel into remote areas is often impeded by mud and swollen rivers. Many conservation activities and community visits are reduced or seasonal. Urban centres remain accessible though outdoor plans are frequently constrained.

Average temperature across Central African Republic in May.
Vakaga, Birao
The first real humidity arrives in May as thunderstorms begin to form on the horizon; when rain falls it is sudden and often heavy, cooling the baking earth and filling seasonal wadis. Roads that were previously dry can become slippery or develop ruts, and chartered flights may be cancelled on storm days. This month is a transitional one: insect activity increases and remote tracks start to degrade, so plan shorter drives and flexible itineraries.
Bossangoa, Kaga‑Bandoro, Paoua
May signals the start of the wet season in earnest across the north-central savanna; heavy afternoon and nocturnal storms become frequent and dirt tracks turn to ribbons of red mud. Rivers and seasonal streams rise quickly, making some bridges and low-water crossings hazardous - arrange 4x4 transport and extra days for transfers. The landscape greens dramatically; birdlife increases but mosquitoes become a persistent concern.
Bangui, Ombella‑M’Poko
May sees the rainy season establish around Bangui with frequent afternoon downpours that cool the city and temporarily disrupt river ferries. Streets can flood in low-lying quarters after heavy storms, so expect occasional delays and muddy paths to riverfront markets. It’s a lively month - greenery returns and urban parks are refreshed - but pack quick-drying clothing and expect higher mosquito activity after dusk.
Bambari, Bria, Ouaka
May is reliably the start of the wet season in the plateaux: heavy afternoon storms are common and unpaved roads quickly become challenging, especially around Bambari. River crossings rise fast and some rural bridges become risky, so book drivers experienced with seasonal conditions. The landscape is spectacularly renewed and waterfalls and rapids start flowing strongly - a treat if you don’t mind mud.
Berbérati, Mbaïki, Bangassou, Lobaye
May marks the wet season onset in the south with frequent heavy rain and soaring humidity that lingers between storms; rivers swell rapidly. Many unsurfaced roads become challenging; trips between towns like Berbérati and Mbaïki often require a 4x4 and local knowledge. The rainforest is lush and active - ideal for birding and botanical studies - but be ready for mosquitoes and reduced overland mobility.
There are no major festivals or events in Central African Republic during May to be aware of.
