Aberdare National Park can be visited throughout the year, but the experience changes considerably with the seasons. Because Tsavo is a semi-arid park with numerous rivers, streams, wetlands and riverine habitats, rainfall has a strong influence on vegetation, road conditions and wildlife distribution. Kenya Wildlife Service describes Kenya’s parks as year-round destinations, while identifying July – December and December – March generally as favorable periods for wildlife viewing; April – May is the principal long-rain period.

Best time according to Moth’s

June – October: Excellent for wildlife viewing

• Generally, one of the most rewarding periods for a classic Aberdare park safari. This is the drier part of the year, when vegetation becomes less dense and animals are often easier to spot across the open plains. As the dry season progresses, wildlife increasingly depends on the park’s permanent wetlands, marshes and other reliable water sources. 

January–February: Warm and Dry

• The weather offers another favorable window for visiting Aberdare National Park. These months fall between the main rainy periods and can provide a good balance of wildlife viewing and green landscapes. There may still be water and vegetation in the wetlands, while the surrounding plains can remain relatively open for game viewing.

March–May: Long-rain season

• The long rains generally occur from March to May, transforming Tsavo normally dry landscape into a much greener and more vibrant environment. Rainfall brings fresh vegetation, replenishes wetlands and creates dramatic seasonal scenery.

November – December: Best for green landscapes, birdlife and a quieter atmosphere

• Bring the shorter rains, which can gradually refresh the landscape after the dry season. The arrival of rain stimulates new vegetation growth, and the plains can become increasingly green. 

The best time to experience Aberdare National Park is throughout the year, as each season offers a unique safari experience.
