When to go
The best time to climb Kilimanjaro
Two dry windows a year — here's what actually changes between them, and why the rainy months are worth avoiding.
Kilimanjaro climbing seasons
| Window | Months | Conditions |
|---|---|---|
| Peak dry season | Jun - Oct | Driest, clearest, most popular — busiest camps |
| Secondary dry season | Late Dec - mid Mar | Dry, quieter than Jun-Oct, warmer at altitude |
| Long rains | Apr - May | Heaviest rain — most operators discourage climbing |
| Short rains | Nov | Lighter but still frequent rain, muddier trails |
Why two separate dry seasons exist
Kilimanjaro sits close enough to the equator that its weather follows Tanzania's two-rainy-season pattern rather than a single winter/summer split — which is why there are two distinct windows worth targeting rather than one long season.
June to October — the busiest window
This is both the driest and most popular stretch, overlapping with Northern Hemisphere summer holidays. Clearer skies generally mean better summit views, but also the most crowded camps on the popular routes like Machame.
Late December to mid-March — the quieter dry window
A shorter but still genuinely dry period, generally quieter on the trails than the June-October peak, with the added appeal of climbing over the New Year for those specifically drawn to that. Late February through early March tends to be the driest stretch within this window.
Why the rainy seasons are usually avoided
April-May (the long rains) brings the heaviest and most sustained rainfall of the year, and most operators either discourage climbs entirely or set expectations accordingly. November's short rains are lighter but still frequent enough to affect trail conditions and summit visibility.
Trade-offs worth knowing about the popular months
The most reliable weather windows are also the most crowded — if avoiding crowds matters more than minimizing weather risk, the days immediately before or after the peak of each dry season (early June, late September/early October, or January) can offer a reasonable middle ground.
Temperature swings by altitude, whatever the season
Season mostly changes rainfall and cloud cover, not the underlying temperature range — the mountain runs from warm rainforest at the gate to well below freezing at the summit on every single climb, in every month. Pack for that altitude range regardless of which dry-season window you pick; see the packing guide below for specifics.
