Arusha National Park’s climate is normally pleasant and mild. It rarely gets hot during the day and it is usually cool to cold at night and in the early morning. It is important to pack warm clothing for use in the evenings and on game drives.

The Dry season is from June to October. The Wet season consists of two rainy periods (the short rains from November to December and the long rains from March to May), with a dry spell in between. Afternoon thundershowers are common in the Wet season, but it would be rare for it to rain all day. Arusha National Park incorporates Mt Meru, which creates a microclimate with more rain and clouds than is typical for the area.
