Due to its proximity to the equator, temperatures in Simien Mountains National Park don’t change much throughout the year. There is, however, a big gap between daytime and nighttime temperatures. Days average at 18°C/64°F and nights at 6°C/43°F.

There is a distinct Dry season (October to April) and a Wet season (May to September). More than half the annual precipitation falls over July and August.

Dry Season October to April

Days are typically bright and sunny and it rarely rains. Daytime temperatures are around 18°C/64°F and nighttime temperatures around 7°C/45°F. Hiking conditions are ideal at this time.

  • October & November – This is the beginning of the Dry season. It might still rain every now and then, but this shouldn’t interfere with your activities. It is a lovely time as the scenery is fresh and green after the rains.
  • December, January & February – It rarely rains and there is a lot of dust in the air. These months are great for hiking, but the scenery can look a bit parched.
  • March & April – The first rains bring relief and the dust settles. Rain shouldn’t be a big problem, but waterproof clothing is recommended.

Wet Season May to September

Some rain can be expected throughout the Wet season and July and August see heavy downpours. Daytime temperatures average at a comfortable 18°C/64°F, but it is about 12°C/22°F cooler at night. Waterproof clothing is essential.

  • May & June – This is the beginning of the rains. It rains regularly but usually not for long.
  • July & August – These are the peak Wet season months. It rains a lot and these months are not recommended for hiking. The road inside the park might deteriorate, and exploration of the higher reaches might be difficult.
  • September – The rain diminishes, everything is looking lush and there are wildflowers everywhere. The sky is free of haze, which makes for spectacular views down the escarpment. This is a lovely month but be prepared for some showers.
