Moshi Kilimanjaro Tanzania
The short answer: The best months are January-February and June-October. These are the dry seasons with clear skies, minimal rain, and the highest success rates. The absolute best month for most climbers is September — dry, clear views, and fewer crowds than August. But “best” depends on your priorities: crowds (avoid August), budget (shoulder seasons), or scenery (green season has beautiful landscapes). This guide breaks down every month so you can choose the perfect time for YOUR climb.
🥇 BEST (Dry & Clear): January, February, June, July, August, September, October | 🥈 GOOD (Shoulder): December, March | 🥉 OK (Wet, but doable): April, May, November
🎯 Our verdict for most climbers: Choose September for perfect conditions + reasonable crowds. Choose January-February for dry season with fewer tourists. Avoid April-May (long rains) unless you’re on a tight budget and don’t mind mud.

📊 Data based on 20+ years of Kilimanjaro weather records and Tanjaro Adventures climb logs (2015-2025).
Why September is our top pick: You get the perfect dry season weather (clear skies, no rain, dry trails) but with fewer crowds than August. Summit views are spectacular. Temperatures are cold but manageable.
The honest truth: April and May are the worst months to climb Kilimanjaro. Heavy daily rain, muddy slippery trails, and summit views are often obscured by clouds. Success rates drop 5-10% compared to dry season.
November is the better wet season option. Rain usually comes as afternoon showers (1-3 hours) rather than all-day downpours. Mornings are often clear.
Kilimanjaro temperatures vary dramatically by altitude. Here’s what to expect at each zone.
| Altitude Zone | Daytime Temp (Dry Season) | Night Temp (Dry Season) | Daytime Temp (Wet Season) | Night Temp (Wet Season) |
|---|---|---|---|---|
| Start (Gate: 1,800m) | 20-30°C (68-86°F) | 15-20°C (59-68°F) | 18-25°C (64-77°F) | 15-18°C (59-64°F) |
| Mid (3,000-4,000m) | 10-20°C (50-68°F) | 0-10°C (32-50°F) | 8-15°C (46-59°F) | 0-8°C (32-46°F) |
| Summit Night (5,895m) | -10°C to -25°C (14°F to -13°F) | Same — summit is always at night | -5°C to -15°C (23°F to 5°F) | Same — wet season slightly warmer |
July, August, September, December (holiday week)
January, February, June, October
March, April, May, November
The wet season transforms the lower slopes into a lush, vibrant paradise. The rainforest is greener, waterfalls are flowing, and wildflowers are blooming.
The dry season offers crystal clear views of the summit and surrounding plains. The air is crisp and visibility is maximum.
Surprisingly, success rates don’t vary dramatically by month — route selection matters much more. But there are differences.
| Month | Success Rate (7-Day Route) | Success Rate (5-Day Route) | vs Dry Season Baseline |
|---|---|---|---|
| January | 85-88% | 65-68% | Baseline |
| February | 85-88% | 65-68% | Baseline |
| March | 82-85% | 62-65% | -3% vs baseline |
| April | 75-80% | 55-60% | -8% vs baseline |
| May | 78-82% | 58-63% | -5% vs baseline |
| June | 85-88% | 65-68% | Baseline |
| July | 86-89% | 66-70% | +1% vs baseline |
| August | 86-89% | 66-70% | +1% vs baseline |
| September | |||
| October | 85-87% | 65-67% | Baseline |
| November | 80-84% | 60-64% | -4% vs baseline |
| December | 83-86% | 63-67% | -2% vs baseline |
September or January

April, May, or November
10-20% cheaper than peak season. Expect rain and mud, but very few crowds.
September (clear views) or May (green landscapes)

April, May, or November
You’ll have campsites almost to yourself. Downside: rain expected.
December (especially Dec 20-Jan 5)
Festive atmosphere, but book 6+ months ahead. Weather is mixed.
July, August, September
Peak dry season = peak success rates (86-89% on 7-day routes).

📩 Not sure which month is right for you? Tell us your priorities (budget, crowds, weather, scenery) — we’ll recommend the perfect month.
September is the best month overall. You get perfect dry season weather (clear skies, no rain, dry trails) with fewer crowds than August. January and February are excellent alternatives.
April, May, and November are the cheapest months (10-20% below peak prices). These are the wet seasons, so expect rain and mud. November is the best of the wet months.
Yes, it’s safe but more challenging. Trails are muddy and slippery (higher injury risk). Summit views are often obscured by clouds. Success rates drop 5-10% compared to dry season. Pack excellent rain gear.
June, July, and August are the coldest months. Summit night temperatures can drop to -20°C to -25°C (-4°F to -13°F). December-February are the “warmest” but still -10°C to -15°C at the summit.
No. Route selection (7+ days) and proper preparation matter much more than which month you choose. A 7-day Machame climb in April (75-80% success) still beats a 5-day Marangu in September (65-70% success).
Yes — August is the busiest month. Campsites are full, trails have many climbers, and you’ll need to book 6-12 months ahead. Choose September for similar weather with fewer crowds.
