Month by month

Best time to visit Tsavo

Late June to October is the pick, peaking in September and October when the bush thins and game crowds the waterholes. January and February are a hot, dry second window. April is the month to avoid.

If you only want the answer

June to September. June here is genuinely rainless, 2 mm on the thirty-year average, against 83 mm in December. Nothing concentrates animals like water that has stopped falling.

Prime Dry but hot Shoulder Green season Bar height is average rainfall, the figure above it is the daytime high.

Climate figures are Open-Meteo climate normals, 1991 to 2020, measured at -3.2, 38.5. Prime, shoulder and green are worked out against this park's own year, not a fixed threshold: the four months with the least rain, the four with the most, and the rest in between. Full charts on the weather page.

Two rainy seasons, two dry ones

Tsavo is genuinely semi-arid, taking only 555 millimetres of rain a year across two wet seasons: the long rains from March to May, peaking in April, and the short rains in November and December. Between them sit two dry windows, and those are when you want to be here.

Temperatures barely move: highs of 28 to 34 degrees all year, lows of 17 to 21. The altitude is low, so days are hot and nights merely mild.

One thing worth knowing about rates

Lodge seasons do not match weather seasons. High season is usually July to October plus a festive peak around Christmas, with green-season rates from April to June. Satao Camp drops from $243 to $135 full board in April, Voi Wildlife from $128 to $95. If you can tolerate wet roads and thicker bush, April and May are half price.
