Are you talking about the upper hose? It's probably normal. That's the hot coolant return from the engine to the radiator.
Shoot it with an infrared heat gun and see what the temp is. Depending on what thermostat you've got, somewhere around 190 degrees is normal.

How hot is "really hot"?

I would say probably. The hose will stay relatively cool until the thermostat starts to open. There is not much flow until this happens so the coolant in the block is absorbing all the heat.
I know on my daily driver, the first stop sign I hit is a little over a mile from my driveway. By the time I get there the gauge is already in its normal spot.
Are you having an overheating problem or is the hot hose something you just happen to notice?

Once an engine reaches operating temperature the upper hose will be way too hot to touch, like I say around 190 degrees and it doesn't take very long to reach operating temp.
Sounds like you have nothing to worry about.
Like Montana said, if you have any doubts, install an aftermarket gauge.
