Dry Seasons: June–September & December–February
The two dry seasons are the most popular times to visit Bwindi. Rainfall is lower, trails are firmer, and the forest is generally easier to navigate. Temperatures are pleasant, ranging from around 7-11 degrees C at night to 20-27 degrees C during the day.
June to September coincides with summer holidays in Europe and North America, making it the busiest period for gorilla trekking. Permits sell out months in advance, and lodge prices are at their highest. December to February is the second dry season and slightly less crowded, though the Christmas and New Year period sees a spike in demand.
During dry seasons, the gorillas tend to range at lower altitudes where food is plentiful, often making treks shorter and less strenuous.
Wet Seasons: March–May & October–November
The long rains fall from March to May, and shorter rains from October to November. During these months, the forest is at its most lush and verdant, streams and waterfalls are at full flow, and the birdlife is particularly active with migratory species present.
Trekking during the wet season means muddier trails, more frequent rain showers, and potentially longer slogs through soft ground. Good waterproof gear is essential. The upside is that permits are easier to obtain, lodges often offer discounted rates, and the forest feels more exclusive with fewer trekking groups.
The gorillas are present year-round regardless of rainfall. Trekking success rates remain above 95% even during the wettest months. If you are flexible and well-prepared, wet-season trekking can be a rewarding and more affordable option.
Month-by-Month Overview
January and February are dry and warm — excellent trekking conditions with moderate visitor numbers. March sees the start of the long rains, with increasing rainfall through April and May. April is typically the wettest month.
June marks the beginning of the main dry season. July and August are the busiest months with the highest demand for permits. September remains dry but visitor numbers begin to ease.
October and November bring the short rains. December is transitional, drying out toward the end of the month as the second dry season begins. Christmas week is very popular.
Temperatures vary more with altitude than with season. The higher sectors (Ruhija at 2,300 m and Nkuringo at 1,900 m) are noticeably cooler than Buhoma (1,500 m) and Rushaga (1,800 m).
Permit Availability by Season
Peak season (July-August, December-January) sees the highest demand. Bwindi issues a fixed number of permits per day — eight per gorilla family across all sectors. With around 20 habituated families, roughly 160 permits are available daily in total.
During peak months, permits can sell out three to six months in advance. During the wet season, permits are often available at shorter notice, sometimes just a few weeks ahead.
If your travel dates are flexible, the shoulder months of June, September, and February offer a good balance of dry weather and permit availability without the peak-season crowds.

February and March tend to be the warmest months. Daytime temperatures in the lower sectors (Buhoma) can reach 27 degrees C, though the forest canopy keeps things shaded.
Summary
The dry seasons (June-September and December-February) offer the best trekking conditions, but Bwindi rewards visitors year-round. Wet-season trips bring lush forests, fewer crowds, and easier permit availability. Book permits early for peak season, or embrace the rain for a more intimate experience.
