Get a heated pool.
I my area most pools are heated and my immediate neighbours run their pools
from mid/late may until late september...even early october some years.
And I’m in Canada....the frozen north
Charlotte, NC unheated pools would have a similar pool season and with a bit of
heating, the pool season can be extended....I’m thinking early/mid april to
mid/late october at least. Possible 7 month pool season.
