Tanzania Weather Guide

What to expect
from the sky.

Tanzania sits at the equator and experiences a warm, relatively consistent climate year-round. Temperatures rarely drop below 15°C or exceed 35°C in the safari areas. The variation that matters for visitors is not temperature but rainfall — when it rains, how much, and what effect that has on road access and wildlife distribution.

The Serengeti experiences two rainfall seasons: the long rains (March–May) and the short rains (November–December). The long rains are the more substantial — sustained rain over several weeks that can make some tracks impassable and disperses wildlife as water is available everywhere. The short rains are typically intermittent — afternoon showers that do not significantly affect game viewing but add dramatic cloud formations to the landscape. Between these rainy periods, the climate is dry, warm, and consistently good for safari.

The Ngorongoro Crater rim sits at 2,286 metres and is noticeably cooler than the plains below — expect temperatures 5–8°C lower than the Serengeti, with mist and cloud a regular morning feature on the rim. The crater floor itself is sheltered and warmer. Kilimanjaro creates its own weather system and generates significant cloud cover that extends south across the northern Serengeti — particularly in the afternoon months of March through May.

The Zanzibar coast has different weather patterns from the mainland. The short and long rains align roughly with the mainland but are moderated by the Indian Ocean. The north coast (Nungwi, Kendwa) is the most sheltered year-round and can be swum in any month. The east coast can have strong onshore winds from June through September. The best beach conditions overall are December–March and June–September.

Monthly Weather Summary

Every month.
What to expect.

January & February — Warm, Short Dry Period
January and February represent a short dry period between the short rains and the long rains. Temperatures are warm — 28–32°C at midday on the plains. Morning starts are clear and cool. The southern Serengeti and Ndutu are green from the short rains and alive with calving wildebeest. This is an excellent photography period — green landscapes, clear morning light, and dramatic predator activity around the calving herds. Zanzibar is at its warmest and calmest — excellent beach conditions.
March — Transition, Long Rains Beginning
March sees the beginning of the long rains. Rainfall is initially intermittent — afternoon storms that clear overnight. The Serengeti is lush and green. The Great Migration herds are moving north across the central plains — one of the most photogenic periods for herd photography. Track conditions in some areas begin to soften. Visitor numbers start declining. March is underrated — better weather than April–May, lower crowds than January–February, and the migration in beautiful full movement.
April & May — Long Rains, Lowest Season
April and May are the peak long rains. Rainfall is sustained and significant. Some tracks become impassable. Some camps close for maintenance. Wildlife disperses widely. Visitor numbers are at their annual lowest and camp prices are typically 30–40% below peak rates. The landscape is extraordinarily lush and green. For experienced safari travellers willing to accept logistical limitations, this is one of the most atmospheric periods to visit — dramatic skies, vivid landscapes, complete solitude, and the lowest prices of the year.
June — Rains End, Dry Season Begins
June marks the end of the long rains and the beginning of the dry season. The Serengeti dries rapidly and grass begins to brown. The Great Migration arrives in the Western Corridor, and the Grumeti River crossings begin. Temperatures are moderate — 24–28°C — and morning starts are crisp. Visitor numbers are rising from the April–May low but have not yet reached July–October peak levels. June is an excellent month — good wildlife, good weather, reasonable prices, and the opening of the crossing season.
July, August & September — Peak Dry Season
The Serengeti is at its driest and most golden. Temperatures are consistent — 25–30°C at midday, 12–15°C at night (particularly July). Morning starts require a warm layer until the sun is up. The Mara River crossings peak in August and September. Wildlife concentrations at water sources are at their most photogenic and accessible. Visitor numbers and camp prices are at their annual peak. Clear skies, dramatic dust lighting, and the most consistently excellent game viewing of the year.
October & November — Shoulder Season, Short Rains
October is an excellent shoulder month — declining visitor numbers from the August peak, still dry in the early part of the month, with wildlife beginning to respond to the first rains. The short rains typically begin in late October or November — afternoon showers that do not significantly affect game viewing but add dramatic cloudscapes. Migratory birds arrive in large numbers in November. The herds begin their return south from the Mara. Camp prices moderate from peak season levels. October is our recommended month for guests who want dry-season quality at slightly lower cost.
December — Short Rains Continue, Christmas Busy
December is a mixed month: the short rains continue but are typically intermittent, the landscape is green and photogenic, and the herds are moving through the central Serengeti toward the calving grounds. Early December is moderate on visitor numbers; Christmas and New Year see a significant increase as European and American families travel. Camp prices at the Christmas period are often equivalent to peak season. The week between New Year and mid-January quietens again. If visiting in December, aim for the first two weeks or after January 7th.
