We have a north facing rear garden and 3/4 of the pool gets the sun through the day in the month of October. We have sunbeds to the front and rear of the pool because not everybody wants the sun all day long. In 6 year of renting we have never found the north facing pool to be a problem with sun light. What you may find is that most people go to the parks through the day and may only use the pool during the evening in which case its dark.
