At least 80
Skin temperature is about 88 degrees F. A pool heated to 88 degrees is almost instantly comfortable.
Use a temperature gun.
Easy! 1000000000 xD
Ordinarily the design temperature for the air in the pool room would be 2 degree F higher than that of the pool water. The usual design temperature for the watre in indoor pools is 84 deg F However if the water temperature is higher then the room air would usually be left at around 86 deg F and the dehumidification equipment would be sized accordingly - using these figures. This will result in a higher rate of evaporation, which will automatically be taken care of by the dehumifier - this is assuming that it has been sized and designed properly. Peter Fenton.

I think it depends on weather the pool is heated. You want the pool to be a temperature that everyone can take. Also, outdoors will depend on the temp of your pool or any outdoor pool.
Around 90 degrees outside and 78 in the pool
The temperature of an olympic pool is kept at 25-28C (77-82F)
The lowest temperature to get in a pool, especially a public swimming pool, is about 70 degrees Fahrenheit/ 21 degrees Celsius.
At least 20 degrees lower than the air temperature.
