How warm should swimming pool water be for a baby?

General info on pool temps:

Most people are comfortable in pool water at about 80F on the low end. Almost everyone is comfortable at 85F. Some people will find a 90F pool starting to be too warm.

Babies, on the other hand, lose a lot of body heat to the water and do not have a fully developed temperature regulation system. Therefore, I would recommend a temp in the high 80's (87F) to the low 90's (92F). This should be comfortable enough for you and your baby to have a good time.

Be careful to watch for signs of coldness: shivering, loss of color in extremities like fingers and lips, etc...

Hope this helps...
