August is part of Kilimanjaro’s long dry season, spanning June to mid-October, characterized by minimal rainfall and predominantly clear skies. This period is ideal for climbing, as it ensures excellent visibility of the mountain’s peaks, though it can bring dry and dusty trail conditions, particularly if winds are present. Research suggests that August is traditionally one of the warmer months on the mountain, with daytime temperatures in the low alpine zone (around 3,000–4,000 meters) ranging from 5–10°C (40–50°F). As climbers ascend, conditions cool significantly; at the high alpine zone (around 5,000 meters), temperatures hover around freezing (0°C / 32°F), and at the summit (5,895 meters), daytime temperatures can drop to -6°C (21°F), plummeting to -20°C (-4°F) at night. With wind chill, it can feel as cold as -30°C (-22°F), necessitating robust cold-weather gear.

The dry conditions can lead to dusty trails, especially on exposed sections like the Shira Plateau, and climbers are advised to use a light buff to protect against dust, particularly if winds pick up. While the western side, including the Shira Plateau, may feel slightly colder, it is not typically a deterrent, allowing for enjoyable exploration of this volcanic area. It’s worth noting that while the weather is generally clear, there may be cloud cover in the forest and moorland zones, and southern routes like Machame can experience occasional rain, though Lemosho, starting on the west, is less affected.

Route Description and Itinerary

The Lemosho Route is widely regarded as one of the most picturesque trails on Kilimanjaro, offering panoramic vistas and a high summit success rate due to its design for acclimatization. Starting from Londorossi Gate, the route begins with a drive from Moshi, followed by a trek through lush rainforests on the first day, reaching the Shira Plateau by day two. The 8-day itinerary, as preferred for August climbs, includes a gradual ascent, crossing the entire Shira Plateau from west to east in a relatively flat hike, before joining the Machame Route near Lava Tower on day 3. This junction marks the point where climbers may encounter more people, as it coincides with day 2 for those on the Machame Route. The route then traverses underneath Kilimanjaro’s Southern Ice Field via the Southern Circuit, summiting from Barafu Camp, and descending via Mweka Gate.

This extended duration is crucial for acclimatization, reducing the risk of altitude sickness, and is often chosen by climbers with varying fitness levels, enhancing the likelihood of reaching Uhuru Peak. The route’s scenic diversity, from tropical forests to alpine deserts, makes it a favorite, with the Shira Plateau offering unique volcanic landscapes and views of Kibo Peak.

Crowd Dynamics and Peak Season Impact

August is undeniably peak climbing season on Kilimanjaro, driven by the combination of favorable weather and summer vacations in Europe and North America. This makes it one of the busiest months, alongside July, with significant crowds, particularly on popular routes like Marangu and Machame. However, the Lemosho Route offers a quieter start, with fewer climbers at the trailhead due to its western approach and relatively recent introduction as a route. This solitude lasts until day 3, when it joins the Machame Route, aligning with day 2 for those climbers, leading to increased encounters thereafter.

The evidence leans toward August being a bustling time, with research indicating it as part of the main climbing season from August to September. This busyness can affect camp availability and trail congestion, especially near shared sections, but the initial days on Lemosho provide a more serene experience, ideal for appreciating the natural beauty without the hustle.

Practical Tips and Gear Recommendations

Given the conditions in August, climbers should prepare for a range of weather scenarios. Layered clothing is essential, with base layers for warmth, insulating mid-layers, and a windproof, waterproof outer shell. A down jacket is critical for summit night, given the sub-zero temperatures, and thermal gloves and hats are advisable. The dry, dusty conditions necessitate a light buff or neck gaiter to protect against dust, especially on windy days, and sunglasses to shield against glare on sunny, clear days.

Hydration is key, as the dry air can lead to dehydration, and climbers should carry sufficient water and use electrolyte supplements. The 8-day itinerary supports acclimatization, with rest days or shorter hiking segments recommended to adjust to altitude. Footwear should be sturdy, with gaiters to keep dust out, and trekking poles can aid on uneven, dusty trails. Given the warmer days, sunscreen and lip balm with UV protection are also essential to prevent sunburn at high altitudes.

Unique Experiences and Considerations

One unexpected detail is the opportunity to experience the Shira Plateau’s volcanic landscapes, which, despite the colder western side, offer stunning vistas and a sense of isolation early in the climb. The route’s gradual ascent through diverse ecosystems, from rainforests with potential sightings of Black and White Colobus monkeys to alpine deserts, provides a rich tapestry for nature lovers. August’s clear skies enhance these views, making it a prime time for photography, though climbers should be prepared for the dust to affect camera lenses, requiring protective measures.

It’s also worth noting that while August is busy, the Lemosho Route’s design helps distribute climbers, reducing bottlenecks compared to more traditional routes. This can enhance the overall experience, offering a balance between solitude and community, especially as groups merge later in the climb.
