Climate of Guinea

Where is the country of Guinea located? The Republic of Guinea is a country in West Africa that borders Senegal, Guinea-Bissau, Mali, Ivory Coast, Liberia, and Sierra Leone. The country is normally referred to as Guinea (English: Guinea). However, to avoid confusion with neighboring Guinea-Bissau, the name Guinea-Conakry is also sometimes used. Guinea’s landscape begins flat in the western coastal region and becomes more hilly inland and locally mountainous in the east. Guinea has a highest point of 1752 meters (Mount Nimba). Guinea has a mix of two tropical climates: the tropical monsoon climate in the coastal areas (type Am according to the Köppen climate classification) and a tropical savanna climate in most of the country (type Aw).

Rainy season

Guinea has a rainy season that starts in April in the interior and lasts until October. Along the coast, the monsoon period starts a little later, usually in the course of May. With rainfall exceeding a thousand millimeters per month in July and August, the coast of Guinea is one of the areas with the most intense rainfall periods in Africa. Even worldwide, there are relatively few areas where so much rain falls within one month. These heaviest rainy months are accompanied by a high number of days in which precipitation falls: an average of 27 rainy days per month. In total, three thousand to more than four thousand millimeters of rainfall per year falls in southwestern Guinea.

Tropical warm

Guinea is located in a zone where tropical temperatures prevail. On average, the maximum temperature along the coast and in the higher areas in the interior is about 28 to 33 degrees. In the lower areas in the interior of Guinea, the mercury rises slightly further. With an average of 36 degrees in Karkan, it is even warmer in the months of March and April. The high relative humidity ensures that you experience the already high temperatures as even warmer and even very stuffy.

Best time to visit Guinea

Do you want to know when is the best time to travel to Guinea? You can determine the best time to travel to a destination based on the weather and climate. In addition, there are other factors that are not directly related to the weather and that can influence the best travel periods for a travel destination. Think, for example, of holidays or festive periods, which makes traveling more interesting or not, because daily life comes to a standstill as a result. The Republic of Guinea is a country in West Africa. The former French colony has a tropical monsoon climate in the west, along the coast. The monsoon climate is also present in the southeast, where the Nzérékoré region is located. The rest of the country has a tropical savanna climate. It is mainly the precipitation statistics that determine the type of climate. Temperatures throughout the country are tropical warm to very warm.

Best months

The best time to travel for the whole of Guinea is from mid November to mid March. In the Nzérékoré region, the amount of rain already starts to increase during March, so that looking at the entire country, we no longer include the second half of March and the entire month of April as the most suitable travel period. If you would not consider Nzérékoré, you can designate mid-November to April as the best time to travel. The combination of warmth, a lot of sun and very little rain makes Guinea especially a good winter sun destination.


The central part of Guinea, especially the northern part that borders Senegal, is very warm in the dry season. Maximum temperatures rise inland in many areas to 35-40 degrees Celsius in the early months of the year. It is only when the monsoon period begins that the maxima drop to more normal values ​​of about 30-32 degrees. In the coastal areas and in Nzérékoré, temperatures are slightly more tempered. There, throughout the year, the mercury is between 26 and 33 degrees on average in the afternoon and temperatures drop to minimums of about 20 to 25 degrees.

Rainy season

The monsoon is a phenomenon that you cannot ignore in Guinea. The rainy season starts in March, April or May, depending on where you are within this tropical country. The monsoon lasts until October or November. Huge amounts of rain can fall in some places during the wet season. The capital Conakry, which is located on the coast, has to deal with rain almost every day in July and August. It then comes pouring out of the air, resulting in more than a thousand millimeters of precipitation per month in the summer months of July and August. More falls in one month than in the Netherlands in a whole year. It is therefore better to avoid Guinea and certainly Conakry when it is summer with us.
