Thanks for playing and asking! Because the Wumpus moves around as you also move throught the temple, the Wumpus could be anywhere in the temple proper. However, there are a few things that will help you discover the location.

SPOILERS BELOW!

There are four altars. Praying at any of them gives you a temporary power that allows you to sense not just whether the Wumpus is in one of the adjacent rooms when you pray (as is typical) but also whether it's in a room adjacent to a room you're in. This disappears after a number of room transitions (I can't remember but somewhere between 5 and 10).

If you pray at all four in a single playthrough, this power becomes permanent.

If you're on the roof of the temple and it's nighttime, when you pray, you will be told if the Wumpus is in one of the rooms directly below you. 

At the deepest/lowest point in the temple (left of the blue area under the red area), there's an area with dirt walls. Go to the end of the passages and you'll find a room with a pool of water. Stand over the pool of water and pray. A tile will appear above your head. This tile is the sort of tile in the room where the Wumpus currently is. If you go to that area, you are likely to find the Wumpus.

I hope this helps!
