Map from Google - Central_African_Republic

In the Central African Republic, a country located south of the Sahara and north of the Equator, the climate is tropical, hot all year round, with a dry season in winter, and a rainy season, which lasts for most of the year in the south, and is limited to the summer months in the north. In the rainiest period, from July to September in the centre-north and from May to October in the south, the rains can cause flooding.
Most of the country is occupied by a plateau, whose altitude ranges between 400 and 800 metres (1,300 and 2,600 feet); in the westernmost part it reaches around a thousand metres (3,300 feet), in the prefectures of Nana-Mbamberé and Ouham-Pendé (see cities such as Bouar and Bocaranga), where also the highest point of the country is found, Mount Ngaoui, at the border with Cameroon, 1,374 metres (4,419 feet) high.
The country is covered by savanna, and in large areas of the south-central also by rainforests; in the far north there is instead a drier strip close to the Sahel.

In the far north, nights are cool in winter, and sometimes they can be a bit cold, while during the day it is hot: maximum temperatures hover around 33/34 °C (91/93 °F), but sometimes they can rise even higher. The wind from the north-east, the harmattan, brings sand particles from the Sahara and raises clouds of dust. Starting from February, the temperature rises, and the hottest time of year begins, in which highs can exceed 40 °C (104 °F), until May. In the second half of May, showers and downpours related to the African monsoon begin to occur, so the temperature drops, but in return relative humidity increases. In October the good weather returns and the temperature rises again, with some hot days, but less than in spring.
Here are the average temperatures of Birao, located in the far north, at 450 metres (1,450 ft) above sea level.

Further to the south, in the north-central region, winter is even hotter, but then the torrid period of spring is less evident, because rains and cloud banks come earlier.

In the north we find the Manovo-Gounda St. Floris National park, a World Heritage Site by UNESCO, unfortunately at risk because of illegal hunting and poaching. The park is home to several animal species such as elephants, leopards, cheetahs, African buffalo, and the West African black rhino, which, however, was declared extinct in 2011.

As we mentioned, in the far west there are areas located at an altitude of around a thousand metres (3,300 feet). Here the altitude tempers the climate, and in summer, at the height of the rainy season, days can be even a little cool.

In Bouar, 1,400 mm (55 in) of rain per year fall, of which more than 100 mm (4 in) per month from April to October, and a maximum of 255/260 mm (10/10.2 in) per month in August and September.
The capital Bangui is located in the south, on the banks of the Ubangi River, at the border with the Democratic Republic of Congo, and at 350 metres (1,150 ft) above sea level (the lowest altitude of the country). Here the temperatures are more uniform throughout the year, however, in winter the temperature range is higher, and during the day it exceeds 30 °C (86 °F). Here too we can notice the heating between February and May, but it's less pronounced that in the centre-north.

Bangui, panorama

The amount of sunshine in the Central African Republic is higher in winter than in summer, and is higher in the north than in the south: in fact, in the north not only the dry season is longer, but it is also more easily sunny, while in the south not only the rainy season is longer, but in winter the sun does not always shine, because cloud banks are relatively frequent.

When to go

The best time to travel to the Central African Republic is winter, from December to February, being the dry season. Days can be hot, especially at low altitudes and in the centre-north. At night, however, it can sometimes be a bit cold in the north. In February, temperatures start to rise, so you may prefer the period from December to January.

What to pack

In winter: in the far north, light clothes for the day, long and made of natural fibres (cotton or linen), turban for the desert wind, a jacket and a sweater for the evening, comfortable boots or sandals. In the south and Bangui, light clothing, a light sweatshirt for the evening, a light jacket for any very cool nights, scarf for the wind full of dust.
In summer: light clothing, long and of natural fabric (cotton or linen); sweatshirt, umbrella or light raincoat for the rain showers. For higher altitude areas (Bouar, Bocaranga), you can add a light jacket.
For women, it is best to avoid shorts and miniskirts.
