The right time to open and close your pool
Closing
CAA-Québec calls October the ideal month. Quebec pool retailers advise closing as late as possible, just before the first frost: end of October, or early November in southern Quebec.
The benchmark: water below 10 °C (50 °F), which slows algae and keeps the water clear until spring.
