In short: July to October for the Great Migration in the Masai Mara, in the height of the dry season, and January and February for a short, quieter dry season. August remains the best compromise for seeing the Mara River crossings, with only 32 mm of rain in the reserve, against 126 mm in April.
Best avoided: April and May: the heart of the long rains, with 126 mm over 17 days in April in the Masai Mara, muddy tracks and some areas of the reserve hard to reach.
