Climbing Kilimanjaro in May – Weather, Conditions & Best Routes (2026 Guide)

Climbing Mount Kilimanjaro in May offers a very different experience compared to the dry-season months. May falls in the middle of Tanzania's long rainy season, which runs from late March to early June. Because of this, it is one of the least popular months for trekking, but it still provides certain advantages such as quiet trails, lush landscapes, and increased solitude for those who do not mind the wet conditions.

Although it is possible to climb in May, the heavy rains and muddy terrain mean that climbers should be well-prepared and aware of the challenges associated with this time of year.

Climbing Kilimanjaro in May: Weather and Temperatures

May is one of the wettest months on Kilimanjaro. Expect persistent rainfall, cloudy skies, and cooler temperatures as you gain altitude.

Rainy Season Conditions

May is deep within the long rainy season

Heavy rain is common, especially in the afternoons and evenings

Trails become muddy, slippery, and slow to navigate

Waterproof gear is essential to stay dry and warm

Temperatures in May

Lower Elevations (Rainforest Zone): Daytime temperatures: 15°C to 20°C (59°F to 68°F). High humidity and dense vegetation

Higher Elevations (Alpine Zone & Summit): Night temperatures often fall below freezing. Rain can turn into snow above 4,500 meters. Wet conditions increase the cold, especially near Base Camp

Visibility

Rain and cloud cover often reduce visibility, which can obscure mountain scenery and summit views. Expect cloudy days, misty forests, and overcast afternoons.

Trail Conditions in May

May brings some of the most challenging trail conditions of the year:

Muddy and slippery paths, especially in the rainforest zone

Higher risk of slips and falls due to wet terrain

Slow progress because of soft, waterlogged ground

Difficult camp conditions, with damp tents and wet gear

Proper waterproof footwear, gaiters, trekking poles, and dry bags are strongly recommended.

Crowds in May

May is considered a low-season month on Kilimanjaro.

Very few climbers on the trails

Campsites feel quiet and spacious

Excellent month for those seeking solitude and privacy

If avoiding crowds is your priority, May offers one of the quietest trekking experiences of the year.

Altitude Sickness in May

Regardless of weather, the altitude remains a major factor.

Kilimanjaro's summit stands at 5,895 meters (19,341 ft)

Proper acclimatization is crucial

Longer routes remain recommended even during the rainy season

Climbers should use a slow pace, hydrate consistently, and choose routes that offer gradual altitude gain.

Best Routes to Climb Kilimanjaro in May

While all routes are technically open, some routes perform better in wet conditions.

1. Rongai Route (Highly Recommended)

Approaches from the drier northern side of Kilimanjaro

Receives much less rainfall than western and southern routes

Offers a quieter, more remote trekking experience

Best choice for May because of reduced mud and better weather

2. Marangu Route

Known for its hut accommodations:

Only route with huts, providing shelter from rain

Advantageous when wet conditions make camping difficult

Shorter acclimatization schedule, so success rates can be lower

Better for those concerned about staying dry

Routes to Avoid in May

Machame, Lemosho, and Umbwe routes

These routes pass through rainforest zones that become extremely muddy and slippery during the long rains.
