Temperatures at the ISS range between 250° F in direct sunlight and -250° F at opposition to the Sun.
You might be surprised to learn that the average temperature outside the ISS is a balmy 50° F or so. This average temperature is above the halfway point between the two temperature extremes because objects in orbit obviously spend more time in partial sunlight exposure than in complete opposition to the Sun.
The wild fluctuations of 500° F around the ISS are due to the fact that there is no insulation in space to regulate temperature changes.
Vacuum is an insulator. The ISS has a heating problem where it cannot dump heat all that well (notice the heat sinks attached to the station). The only method to dump heat is by radiation which is one of the slowest methods.
