Guinea in September

November through March delivers Guinea at its best. The harmattan winds blow away humidity, temperatures drop to comfortable levels, and roads become passable. December and January offer perfect highland weather — cool mornings, warm afternoons, clear skies for mountain views. But here's the trade-off: this dry season also brings dust storms that can ground flights and irritate sinuses. The rains from May to October turn Guinea green and spectacular, but also turn roads into muddy obstacles. Waterfalls rage at full power during rainy season, creating the most dramatic scenery. Just prepare for delays, cancelled transport, and humidity that makes everything stick to your skin.
