Reading it takes ten seconds: 52 dots, one per week. Solid teal is Provo's swim season; the hollow teal run before it (April 24 to May 15) is when to open; the hollow amber run after is when to close, with October 10 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.

Closing — deadline October 10

Hold the cover until September 30, then winterize by October 10, a week ahead of the October 21 freeze normal. Late and cold beats early and warm.
