You want waterproof everything, gloves, coat, pants, and shoes. Dress in layers. The weather can be very variable. I was there at the end of July, so it was not super cold, but there was plenty of rain. Bring protection for your camera and cellphone as well.
I'll definitely second the rain protection for your camera & lens as well as the cell phone. For rain protection for my camera & lens combo, I use the OpTech brand. I forget what it's called exactly. Just type "OpTech rain cover" in the B&H search bar. They are clear, inexpensive, weight "nothing", and come in 2 or 3 lengths.
