Climate shifts with altitude, region, and season — rainfall matters more than heat for safari planning.

Tanzania weather

What to expect
from the sky.

Tanzania sits near the equator, so temperatures stay fairly steady. In most safari areas you rarely go below about 15°C or above about 35°C. What changes your trip more is rainfall — when it falls, how heavy it is, and how that affects roads and where animals gather.

The Serengeti has two wet windows: long rains (March–May) and short rains (November–December). Long rains can soften tracks and spread wildlife as water is everywhere. Short rains are often afternoon showers that still leave good game viewing, with dramatic skies. Between them, conditions are usually dry and reliable for safari.

Ngorongoro’s rim (about 2,286m) runs cooler than the plains — often 5–8°C lower, with misty mornings. The crater floor is warmer and more sheltered. Kilimanjaro builds its own weather and can push cloud south over the northern Serengeti, especially in wetter months.

Zanzibar follows similar rain seasons but feels milder by the ocean. North coast beaches (Nungwi, Kendwa) swim well most of the year. The east coast can be windier June–September. Strong beach months are often December–March and June–September.

By region

Same country.
Different feel.

Northern circuit

Serengeti plains

Warm days, cool mornings in dry season. Wildlife viewing is strongest when water is scarce and animals hold near rivers and pools. Long rains bring green grass and softer roads.

Highlands

Ngorongoro rim

Pack a warm layer for early crater descents. Mist and cloud are normal on the rim; the floor is calmer and warmer once you drop inside.

Coast

Zanzibar

Humidity is higher than the parks. Choose north or east coast by season — calm swimming most months in the north; windier east coast mid-year.

Monthly summary

Every month.
What to expect.

A warm dry window between short and long rains. Plains often hit 28–32°C by midday; mornings start clear and cooler. Southern Serengeti and Ndutu stay green after the short rains, with wildebeest calving and strong predator activity. Excellent light for photography. Zanzibar is warm and usually calm for beaches.
Rain starts as afternoon storms more than all-day soak. The Serengeti is lush; herds move across the central plains. Some tracks soften. Crowds drop. March is often underrated — better weather than peak long rains, fewer people than Jan–Feb, and migration still photogenic.
The wettest stretch. Some tracks close; a few camps shut for maintenance. Wildlife spreads out. Guests and prices are lowest of the year — often 30–40% below peak. Expect dramatic skies and deep green landscapes. Best for travellers who accept flexible routing for solitude and value.
Rains ease and grass browns quickly. Migration reaches the Western Corridor; Grumeti crossings start. Days around 24–28°C with crisp mornings. Crowds rise from May lows but stay below July–October. Strong mix of weather, wildlife, and price.
Golden, dry Serengeti. Midday about 25–30°C; nights can drop to 12–15°C in July — bring a warm layer for dawn drives. Mara River crossings peak August–September. Animals concentrate at water. Clear skies and reliable viewing — also peak crowds and rates.
October keeps much of dry-season quality with fewer guests. Short rains often arrive late October or November as afternoon showers — still good for game drives, with cloud drama and arriving migratory birds. Herds begin shifting south from the Mara. Prices ease from peak. A favourite for dry-season feel at slightly lower cost.
Showers continue but are often intermittent; landscapes stay green. Herds move through the central Serengeti toward calving grounds. Early December is quieter; Christmas and New Year fill camps and lift rates toward peak levels. Prefer the first half of the month, or after about 7 January, if you want space.
