Guinea’s Climate Overview
Guinea has a tropical climate that’s hot and humid for most of the year. There are two main seasons: the wet season and the dry season. The wet season, caused by the African monsoon, runs from May to October. During this time, heavy rains and high humidity can make travel less convenient. The dry season lasts from November to April and is much more comfortable for travel, with lower humidity and cooler mornings and evenings.
The country’s coastal areas tend to be more humid, while the inland and higher-altitude regions can get cooler. Guinea’s diverse landscape—ranging from coastal areas to rolling hills and mountains—means that temperatures and weather conditions can vary quite a bit depending on where you are.
Best Times to Visit Guinea
For most travelers, the best time to visit is during the dry season (November to April). This is when roads are more accessible, outdoor activities are easier, and you won’t have to worry about heavy rains. Meanwhile, if you don’t mind some rain and want to experience lush landscapes and have fewer crowds, visiting during a shoulder month like November or April can also be a good option.
If you’re planning a beach visit, March to May might be the most pleasant because the coastal winds keep things comfortable, even when it gets hotter inland. For hikers or those planning to explore the mountains in the Fouta Djallon region, the dry months of December to February are your best bet, when temperatures are cooler and trails are not waterlogged.
What to Pack for Each Season
For the dry season (November to April), bring light, breathable clothing since days are generally hot. Nights can get cooler especially in high-altitude areas, so pack a light jacket. Sunscreen, sunglasses, and a wide-brimmed hat are essentials.
For the wet season (May to October), pack waterproof gear like a rain jacket and hike-friendly boots. Mosquitoes are more common, so bring insect repellent and wear long sleeves and pants. You’ll also want quick-drying clothes because it will be humid.
Guinea’s Weather in January
January is one of the coolest months with average temperatures ranging from 18°C to 30°C (64°F to 86°F). This is the perfect time to visit if you want to avoid the extreme heat and humidity. The skies are generally clear, and it’s an excellent time for hiking in the mountains or visiting cultural sites.
Guinea’s Weather in February
February temperatures start to rise slightly, with daily highs close to 31°C (88°F), but early mornings and evenings remain cool.

Guinea’s Weather in March
March is warm, with temperatures often reaching 33°C (91°F) in the afternoons. While it’s hotter, it’s still the dry season, and the cooler coastal regions may offer a more relaxing atmosphere. Make sure to keep hydrated and use sun protection if you plan on outdoor activities.

Temperatures stay between 24°C and 32°C (75°F to 89°F), but it feels hotter because of the humidity. This isn’t the best month for travel if you’re dead-set against rain, but it’s when the country’s lush greenery begins to thrive.
Guinea’s Weather in June
June is fully into the rainy season with frequent heavy downpours. Daytime highs stay around 31°C (88°F), but the constant rain and humidity make it feel warmer.

July is one of the wettest months. Heavy rains are common, and temperatures hover around 31°C (88°F) during the day. Road conditions can get worse, limiting travel options. If you happen to be traveling during this time, staying around major cities like Conakry will make things easier.
