An unfamiliar place is on the weather and temperature on my iphone 6.
How do I remove it and put my own city?

Initiate the weather app. Swipe to the left on the city or cities you want to delete to delete them. Tap on the + sign in the upper right corner to add your city. Enter either the zip code or the city and State.
