May marks the transition from the long rainy season to the main dry season in Bwindi Impenetrable Forest. While rainfall remains frequent, it gradually decreases compared to March and April, with monthly totals averaging between 120 and 170 mm. Across Bwindi’s four trekking sectors—Buhoma, Ruhija, Rushaga, and Nkuringo—the rainforest reaches its peak in lushness, creating spectacular scenery that few other months can match. Visitor numbers remain low, gorilla permits are easy to secure, and by the end of the month, improving weather offers the first signs of the approaching dry season.

Daytime temperatures generally range from 20°C to 24°C, while nights remain cool at around 13°C–14°C. May offers an excellent balance between vibrant rainforest landscapes and steadily improving trekking conditions, making it one of Bwindi’s most underrated months.

Weather and Landscape in May

May brings a gradual change in Bwindi’s weather. The first half of the month often continues the pattern established in April, with regular afternoon showers, damp trails, and high humidity. As the month progresses, rainfall becomes less frequent, mornings become brighter, and longer dry periods begin to emerge across the forest.

The landscape reaches its most vibrant stage of the year. Months of abundant rainfall have transformed the rainforest into an extraordinary display of life. Ancient trees are covered in thick mosses and lichens, ferns spread across the forest floor, orchids cling to towering branches, and fresh vegetation fills every available space. Rivers and waterfalls continue flowing strongly, while mist regularly drifts through the valleys during the cooler morning hours.

Lighting conditions also improve toward the end of May. Overcast skies during the first weeks provide soft, even light ideal for photography, while clearer afternoons later in the month allow shafts of sunlight to filter through the canopy, creating dramatic rainforest scenes.

Gorilla Trekking in May

Gorilla trekking conditions improve steadily throughout May. Early in the month, trails may still be muddy and slippery after weeks of heavy rainfall. However, by the second half of May, the ground begins to dry, making hiking noticeably easier while the rainforest remains beautifully green.

The mountain gorillas continue to benefit from abundant food sources created by the rainy season. Fresh shoots, leaves, fruits, and herbs are plentiful throughout the forest, and gorilla families often remain within productive feeding areas. While trekking times always vary depending on the movements of individual groups, the availability of food can sometimes reduce the distances the gorillas travel each day.

One of May’s greatest strengths is the overall rainforest experience. The combination of active wildlife, flourishing vegetation, flowing streams, and relatively low visitor numbers creates a peaceful atmosphere that many experienced travelers consider one of the most rewarding times to explore Bwindi.

Best Activities in May

May is an excellent month for gorilla trekking, birdwatching, guided forest walks, and nature photography. The forest supports exceptional biodiversity during this period, with colorful birds, butterflies, monkeys, and numerous plant species thriving in the moist environment. Waterfalls remain impressive following the rainy season, while improving weather makes longer nature walks increasingly enjoyable.

Cultural visits to surrounding communities are equally rewarding, offering opportunities to learn about local farming practices, traditional crafts, and daily village life during an important harvest period.
