Scientists have observed that we do not know the highest temperature on uranus. for all we know there is no restrooms on the planet so we have no further information for you at this moment hope you found this helpful.
The mean surface temperature of Uranus is 76 Kelvin.
-210
Ave/max temperature: -200°C Minimum temperature: -214°C
The average temperature of the surface of Uranus is -371.2 degrees Fahrenheit.
The lowest surface temperature is Jupiter. 
The surface temperature of Omega varies slightly. On average, the maximum surface temperature is 760 degrees Celsius, which converts to 1400 degrees Fahrenheit.
Miranda, Uranus' moon is an extremely cold moon. Its mean surface temperature hovers around -305 degrees Fahrenheit. Miranda is 80,620 miles from its planet.
Ave/max temperature: -200°C Minimum temperature: -214°C
The average temperature of the surface of Uranus is -224° Celsius.
The average temperature of the surface of Uranus is -371.2 degrees Fahrenheit.
Maximum temperature: 57KMinimum temperature: 47K

Pluto is no planet anymore. All planets have very different temperatures at the surface. Mercury's Maximum Temperature 465°C (870°F) Mercury's Minimum Temperature -184°C (-300°F) Venus' Average Temperature 449°C (850°F) Earth's Average Temperature 7.2°C (45°F) Mars's Maximum Temperature 36°C (98°F) Mars's Minimum Temperature -123°C (-190°F) Jupiter's Average Temperature -153°C (-244°F) Saturn's Average Temperature -184°C (-300°F) Uranus' Maximum Temperature -184°C (-300°F) Neptune's Average Temperature -223°C (-370°F)
A: Earth has a minimum surface temperature of -88°C and a maximum surface temperature of 58°C.
You should be aware that the gas giants don't have a surface on which you can stand - on Earth, such a surface would be used as a reference. The coldest part of Uranus's atmosphere has a temperature of about 49 kelvin, but as you go further down into the planet, the temperature rises.
The surface temperature of Omega varies slightly. On average, the maximum surface temperature is 760 degrees Celsius, which converts to 1400 degrees Fahrenheit.
400 oC
Uranus has a gas surface
Maximum what? :S
