I think the key words in your question are "at room temperature". See, room temperature is less than body temperature. Heat energy wants to go from a higher temp region to a lower temp region. But, water absorbs heat energy at a faster rate than air. So, the cooling feeling (or transfer of heat away from your body into the surrounding medium) is greater in water than in air. Now, turn on a fan and have more air, thus more cooling medium moving over you taking heat away and it will feel cooler even inf the air is at the same room temperature.

The specific heat capacity of water is high and thermal conductivity is poor.
Water takes longer time to heat up and takes longer time to cool.
Thus water may be at high temperature than the room temperature and some time it may be at low temperature depending upon the maximum and minimum temperature of the room during the day and night.
Only thermometer can judge the temperature and our touching sense may mislead us in judging the temperature.

You will feel that water is colder even the same temperature to the room temperature because water is more efficient in absorbing heat from your body.
Or you can say that heat transfer is better on water than air.

Water has a higher specific heat than air, meaning that it takes more energy from the sun, heaters, etc. to heat the water up than air.

Two reasons:
(1) higher specific heat of water
(2) evaporation of water
