September falls within Kilimanjaro’s long dry season (June to mid-October), delivering mostly clear skies, dry trails, and excellent visibility—ideal for soaking in mountain vistas. At the trek’s base, daytime temperatures hover around 21°C (71°F), cooling off at night. As you climb, the low alpine zone (3,000–4,000 meters) sees mild daytime averages of 5–10°C (41–50°F), while higher up, above 5,000 meters, temperatures near freezing (0°C / 32°F) are common. At the summit, expect daytime lows of -7°C (20°F) to -23°C (-10°F), with nighttime wind chill potentially dropping it to feel like -30°C (-22°F). Though rare, sudden weather shifts can occur, so versatility in gear is essential. The dry conditions mean less mud but more dust, particularly on exposed sections like the Shira Plateau.

Crowds and Atmosphere

September is a busy month on Kilimanjaro, though slightly less crowded than the peak summer rush of July and August, as it aligns with the tail end of international vacation seasons. The Lemosho Route starts with fewer climbers, offering a peaceful beginning, but expect increased foot traffic after merging with the Machame Route. Opting for the 8-day plan allows faster groups to push ahead, often leaving you with a more relaxed pace and a higher chance of summiting—unlike the 50–60% annual success rate across shorter itineraries. The vibrant energy of fellow climbers adds to the experience, balanced by quieter early days on this less-traveled path.

Unique Highlights

The clear September skies amplify the route’s scenic appeal, from rainforest trails teeming with birds and occasional monkey sightings to the stark beauty of the Shira Plateau’s volcanic terrain. Higher altitudes above 5,000 meters feel warmer than earlier dry-season months, enhancing comfort during the ascent. The extended itinerary also offers a chance to connect with the mountain’s rhythm, with rest days built in to marvel at Kibo Peak or spot wildlife like the Black and White Colobus monkeys in the lower zones.

Practical Tips and Gear

• Acclimatization: The 8-day schedule is ideal for adjusting to altitude. Take it slow, hydrate generously (3–4 liters daily), and use rest days to recover. This approach counters the mountain’s low overall success rate.

• Gear: Pack warm layers (base, fleece, down jacket), a waterproof shell, sturdy boots, and trekking poles. A buff helps with dust, while sunglasses and sunscreen protect against UV rays. A sleeping bag rated for -20°C is a must for summit night.

• Training: Build endurance with cardio (running, cycling) and strength (hiking with a weighted pack) to handle the 70 km round trip and 4,900-meter elevation gain.

Why September is a good time

September’s blend of dry weather, mild temperatures, and slightly reduced crowds compared to August makes it a sweet spot for the Lemosho Route. The clear views of Kilimanjaro’s snow-capped summit and the chance to experience its ecosystems in full clarity elevate the journey. While trails like Machame and Marangu buzz with activity, Lemosho’s early solitude and acclimatization focus offer a rewarding climb for those willing to invest the time.
