Reading it takes ten seconds: 52 dots, one per week. Solid teal is Garland's swim season; the hollow teal run before it (March 5 to March 26) is when to open; the hollow amber run after is when to close, with November 9 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
