my tip to you is to go to the swimming pool in the
morning.
the water is the cleanest, cool and shiock! the changing
room/shower toilet shld be quite clean too because you are the
first few to use.
saturday/sunday afternoon or evening/night is the most dirty
because most of people(children...etc) go to the pool during
weekends. most of the time, u will feel that the water is a bit
warm...(hmm body temp or liquid frm body into the pool?)
