Guinea — Weather
Most of Guinea enjoys a tropical climate, especially the coastal region and inland areas. The weather is pleasant all year long, with highs averaging 84°F and lows averaging of 73°F. The rainy season typically lasts from April to November, and the country receives an annual rainfall of up to 170 inches. In the Haute Guinee region (near the border with Mali) temperatures are warmer, and rainy season is shorter.
Best Time to Visit Guinea
Weather-wise, the best time to visit Guinea is between November and December, just after the rainy season and before the dusty harmattan winds strike and blur the incredible views. The rainy season may render minor roads impassable, though it also does the surroundings good, making the countryside greener, the waterfalls more spectacular and the temperatures more pleasant.
