Temperature gauge reads signals off the coolant temperature sensor. It can also point to a faulty thermostat. If your car runs rough in cold, idles rough and uses up more fuel then coolant temperature sensor is your problem. They are normaly a cheap and easy diy to do.
More information is needed before this question can be answered. Is that "temperature"? Are you talking about the temperature gauge? And what is it on? A car? A refrigerator or freezer? The thermostat? The world outside?
If you temperature gauge is going up and down then you may have a problem with your sensor. You should take your car to a professional to ensure that you don't overheat your car.

1. temperature sensor could be going bad 2. thermostat misbehaving 3. instrument panel malfunction you can test the temperature sensor with an ohm meter and placing it in hot water. should only be 20 bucks just replace.
The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens.

It is normal for a temperature gauge to go up a little bit until the thermostat opens up and the cooling fan comes on. As long as it is not going out of the normal temperature range it is fine.
