Janet, that is probably the difference between going in the summer and going in October. When we stayed at SSR one August, I got in the pool to cool down and immediately had to get out again as it was just like getting into the bath and it actually made me warmer. I suspect the outside (air) temperature has a lot to do with it and, obviously, the water will be warmer in the summer when the air temperature is higher.
Personally, I am one of those people who only get into the pool to cool down so it is absolutely no good for me.
I tend to stick to sitting next to the pool with a cold drink instead
