Month by month
Tsavo in May
May is the landscape month. The long rains thin out into a handful of big isolated storms, the park is greener than at any other point of its cycle, and the crowds have not yet remembered that the dry season is close.
If you only want the answer
May is a green, cheap shoulder that strengthens by the week. The final ten days give you a preview of June's viewing at green-season prices, which is the best value equation on the Tsavo calendar.
Rain in exit mode
The card shows 42 mm falling on just 3 rain days, so the total looks wetter than the experience: most May days are dry, and when rain comes it arrives as one big theatrical storm rather than a wet week. Highs ease to 29.6°C and nights to 20.7°C, the most comfortable pairing since the previous June.
That pattern is the difference from April, and it is worth naming plainly: the two months share the green landscape, but May swaps April's persistent wetness for occasional drama, and the roads recover between events.
A park in recovery
This is Tsavo at its most photogenic in the wide sense: red soil under green flush, calves and fawns in the herds, and light scrubbed clean after every storm. Game is still dispersed, but the drift back toward permanent water starts as the outlying pans shrink, and the East's open plains dry ahead of the West's spring country.
Most lodges hold green-season rates through May and into June, so the pricing advantage outlasts the rain by weeks.
The timing play
Aim late. A trip built on the final week of May costs April money and delivers something close to early-June viewing, and availability is still wide open at that point.
Use the quiet to organise the rest of your year as well: July to October inventory at the waterhole lodges is selling right now, so lock those dates before you leave home.
