Fan clutch or water pump

Welcome to 2CarPros.

First, it is normal when the vehicle is hot, turned off, and then restarted for the gauge to be higher. That is because circulation in the cooling system has stopped and the coolant heats up.

Now, if the car doesn't overheat at highway speeds, then I would suspect the fan clutch. Here is a link that shows how it works:

With the engine off, see if it is easy to turn the fan. Do this when it is warm under the hood. It should be somewhat difficult. There should be a good drag when turning it. If it turns freely, replace it.

If you determine the clutch is bad, here are the directions for replacement. The attached pics correlate with these directions.
