For psychological well-being, closing a pool has to be timed right. One must not close the pool before Labour Day. That’s just wrong.
It doesn’t matter how cold, wet, or windy August becomes, winterizing the pool before Labour Day can be classified as disrespect for the seasons.
Yet, if one waits too long, the rainy autumn days might take over and lead right into wet snowy days with only a slight chance of Indian summer. One doesn’t want to close the pool in a snowstorm. Cold wet hands are more painful than the word ‘winterize.’
