Jupiter is a gas giant. This means that it has a huge atmosphere, a liquid mantle, and a liquid / solid core, with no definite boundary between the layers.
The core of Jupiter is probably composed of liquid rock, at a temperature as high as 24,000 K (43,000 °F). The core is small relative to the planet, about 20% of its radius, but it is still fifteen times heavier than the Earth.
Next comes a layer of liquid hydrogen that is under the pressure of 10,000,000 Earth atmospheres. This changes the nature of the hydrogen in such a way that it is able to conduct electricity as metal does, so it is called "metallic hydrogen." This generates the planet's magnetic field which is 20,000 times stronger than Earth's. This layer also makes up most of the planet
The layer on top of this is ordinary liquid hydrogen. This composes the upper 25% of the planet.
Next, the hydrogen thins out into the gaseous atmosphere which is 1000 km (620 miles) deep. It is composed mainly of hydrogen and helium with trace amounts of methane, water, ammonia, and hydrogen sulfide. Some scientists believe that there are also polysulphur compounds and phosphine which lend their colors to the clouds.
Ammonia freezes in the low temperature of Jupiter's upper atmosphere (-125° C/-193° F), forming the white cirrus clouds—zones, ovals, and plumes—seen in many photographs of the planet transmitted by the Voyager spacecraft. At lower levels, ammonium hydrosulfide can condense. Colored by other compounds, clouds of this substance may contribute to the widespread tawny cloud layer on the planet. The temperature at the tops of these clouds is about -50° C (about -58° F), and the atmospheric pressure about twice the sea-level atmospheric pressure on earth. Through holes in this cloud layer, radiation escapes from a region where the temperature reaches 17° C (about 63° F).

I just read about the planet Jupiter. The article was in the discover magazine, but it did not say how hot Jupiter is. It is mainly made up of "hydrogen and helium wrapped under layers of clouds" and the size of Jupiter is 11 times larger than Earth. It has many, many moons around it. Hope this helps.

Hi. Very cold in the outer atmosphere, Earth like temperatures at deeper levels, and probably very hot near the core.

The mean temperature on Jupiter is -110°C (-166°F).

-110°C (-166°F). Not hot at all. Cold enough to turn methane into liquid.
The core is 23,871°C (43,000 °F)

The effective temperature is -234 "F as listed below.
Pretty chilly in my view.
