Temperatures on Mars average about -81 degrees F. However, temperature's range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F. over the lower latitudes in the summer.
What's the warmest it gets on Mars?
A summer day on Mars may get up to 70 degrees F (20 C) near the equator - with the highest temperature shown by NASA at a balmy 86 degrees F (30 C).
Is Mars too cold to live on?
Based on the modelling, the research demonstrates there's only about a two-week period (in Earth time) where they can persist on the surface. They are also extremely cold, at around -50 degrees Fahrenheit, which is considered far too cold for the life we know of to survive.
