How Does Weather & Best Time Work in Tanzania?
Last verified: 2025-06 · Africa & Oceania
1The Quick Answer
The best time for safaris is June–October (dry season, Great Migration peak); January–February is excellent for Kilimanjaro and Zanzibar beaches with hot, sunny conditions.
2What You Need to Know
Tanzania has two rainy seasons: the long rains from March to May (heavy, some parks inaccessible) and the short rains from November to December (lighter and less disruptive). The dry season from June to October is peak safari season — the Great Migration river crossings in the Serengeti occur July through October, and wildlife concentrates at waterholes making game viewing exceptional. Kilimanjaro is best climbed January–March and June–October, avoiding both rainy seasons. Zanzibar has its driest, windiest conditions June–September — ideal for kite surfing at Paje but cooler than ideal for beach holidays. January and February offer warm, calm conditions perfect for beach time and Zanzibar snorkelling.
3Practical Tips
Practical Tips
- 1Book peak season safaris (July–October) at least six months in advance — the best camps in the Serengeti Migration zone sell out quickly and prices are highest during this window.
- 2The shoulder season of January–February offers lower prices, fewer tourists, and excellent wildlife viewing as short-grass plains from the short rains are still lush.
- 3If Kilimanjaro is your primary goal, January–March gives the clearest summit views and most stable conditions — avoid the April–May long rains entirely.
Important Warning
Attempting Kilimanjaro during the March–May long rains significantly increases the risk of summit failure due to snow, ice, reduced visibility, and dangerously slippery trails.
