Seedfork said:You want to keep your compost moist, not soggy but not dry. It is the living organisms that break down the compost, and they will die if the pile is allowed to dry out. So you water if as often as needed to keep it moist.
Seedfork said:If it takes watering it everyday to keep it moist then you might want to water it everyday, or you might consider finding additional sources of compost materials that will retain more moisture.

Edited to add: Maybe even some soil.

When I start a new compost pile up north, I have two, I always dig out the bottom of the container down about four inches.
That way water does not run off and the bottom is cooler and always moist in very hot dry weather.
