When is the best time to go to the Omo Valley?
The rainy season in the Omo Valley differs from much of the rest of Ethiopia. In most parts of the country, the heaviest rain occurs in April and then again in July and August. However, in the Omo Valley there is one longer rainy season from the end of March through to June, and then a shorter rainy season in October. At this time, the roads in the region can be seriously impacted, and completely blocked in some cases, which makes travel a lot more difficult.
Temperatures during the summer months of June, July and August can reach up to 40°C (although they are usually closer to 30°C). The best time to travel is therefore between November and March, to avoid the rainy season and benefit from the milder temperatures, but visiting between June and September also works well (although temperatures will be higher).
