Reading it takes ten seconds: 52 dots, one per week. Solid teal is Binghamton's swim season; the hollow teal run before it (May 13 to June 3) is when to open; the hollow amber run after is when to close, with September 23 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.

Hold the cover until September 13, then winterize by September 23, a week ahead of the October 11 freeze normal. Late and cold beats early and warm.
