Do people with dry or sensitive skin wash their face with water even in the summer?

I've heard that unless you have severely oily skin, it's best to just wash your face with water in the morning. Do you still wash your face with water even in the summer like this? I have dry and sensitive skin, and since I use foam cleanser morning and evening, my skin feels like it's getting too sensitive, so I'm considering trying to wash my face with just water.
