Noticed warm water comes out of cold faucets. Why?

Noticed it last night in the shower and today the wife mentioned it after using the bathroom sink and kitchen sink. Hot water faucet delivers good hot water and I haven't messed with anything since we have been camping regularly. Any thoughts? I was wondering if maybe the water is just warm because it's in the mid 90's with heat index of 100 to 105 but it feels unusually warm.

    Most trailer water tanks are on the bottom of the trailer. right over the hot black roadway. kinda like free hot water.

    or....if you are using water from the campground through a hose...the water in the hose is getting heated by the sun/ambient temperature.

    When you put water in a tank and the tank is inside of a hot trailer that water will be as warm as the temp surrounding the tank. Sounds like the water could be 90 to 100 degrees +.

    Yes, the water will feel warm.

    I suspect the outside temp is the cause. If you run it long enough to clear out your water hose and the inside lines in the RV, it will get cooler. Water in a hose gets VERY hot. If it's from a RV tank, it will be at ambient temperatures not very long after you fill it.

    On the plus side, your water heater doesn't have to do a lot of work. :D

    It could be that the ambient temps are so high that the water in the tanks
    are quite warm. The last 3 trips I made, the temps were > 90F and I have not
    switched on the water heater - the showers are not cold bit not hot either.
