Nanyuki weather in short
Nanyuki lies at about 1,947 m on the equator, so the days are mild and the nights are cool. The year has two rainy seasons. The long rains fall from March to May, and the short rains from October to December. The months between them are drier, and that is when most visitors come.
Rain also varies from place to place. In the short rains of 2025, the Nanyuki weather station recorded 231.8 mm, and the Ol Pejeta Kamok station recorded 485.7 mm. These are totals for one season in one year, but they show that the conservancy can be much wetter than the town. If you plan an early start, see the Ol Pejeta day trips and check the forecast the day before.

Best time to visit Ol Pejeta
The answer depends on what you want from the trip.
| Goal | Months | Why |
|---|---|---|
| Wildlife viewing on dry tracks | June to October | Dry phases make animals easier to find, and this is the conservancy's high season |
| A second dry window | January to February | The other high season, with low rainfall in nearby Nyeri |
| Camping with fewer road problems | Outside April, May, September and October | 4WD is needed to reach the campsites in those rains |
| Wetter trips | March to May, October to December | Rains are heavier, and roads and tracks can be muddy |
For most visitors, June to October, or January to February, is the better choice. No month guarantees dry weather or any particular sighting.

Planning around the rain
What changes on the ground.
Campsite access
In the rains of April and May and of September and October, you need 4WD to reach the campsites. Details are in the hotels and camps guide.
October to December 2026
A stronger rainy season is expected in Kenya in these months because of El Niño, with possible floods and landslides. This is a forecast for the country and not specific to Ol Pejeta. Check road conditions with your driver or lodge.
Driving hours
The gates are open from 07:00 to 19:00, and private driving after 19:00 is not allowed. In the rains, build in extra time for the drive from Nairobi, which normally takes 4 to 4.5 hours. See getting there.
