The best time to go to Athi River is during the dry seasons, which run from January to March and July to October.These periods offer the most pleasant weather for exploring the area and enjoying outdoor activities. The skies are generally clear, and temperatures are warm but not excessively hot, making it ideal for safari excursions or visits to nearby national parks.For travellers interested in wildlife viewing, particularly the Great Migration in the Maasai Mara (which is a longer day trip or overnight stay from Athi River), the dry season from July to October is particularly good. Animals are easier to spot as they congregate around water sources, and the vegetation is less dense.If you're planning a trip focused on relaxation or business in Athi River itself, either dry season is suitable.
