Welcome to inland winds! It is hardly ever what the forecast says. That said - if you can fly in those conditions - you can pretty much fly anywhere! Low wind flying is an art, a skill, only learned by doing. Can it get frustrating? You bet. No fun going out , setting up, and not enough wind to fly.
Good equipment helps, or rather the correct equipment. Yes, a light wind kite would work better in the conditions you describe. So will light and/or short lines. But the biggest tool is you! Knowing your gear is part of the battle, but knowing the techniques for low winds is all up to you. And it is only learned by putting your time into it.
