* Climate: Giraffes in hot, dry climates will drink more water than those in cooler, wetter regions.
* Diet: Giraffes get a lot of moisture from their diet of leaves, which can reduce their need to drink.
* Individual variation: Just like humans, some giraffes might drink more or less than others.
It's important to note that this is just an average, and the actual amount of water a giraffe drinks can vary significantly.
