Welcome to the Hunt-WA bear hunting crew. Speaking for my own experiences with the stalk and spot method, I have always had good luck in the West side higher elevations 3000ft + around the second week of August when the berries are really coming in. Then after that it always seems to a significant lull in their activity again until mid October or so when the period of Hyperphagia sets in for the bears and they are very active once more prior to hibernation, so that is another good opportunity to hit the bear hunting hard once more. The key is glassing often and lots of patience while glassing, I like to spend 2 to 3 hours per area studying for sign in a good spot, looking for unusual movement on tree braches and limbs relative to normal wind currents down in the mast foliage.
