Reading it takes ten seconds: 52 dots, one per week. Solid teal is Santa Fe's swim season; the hollow teal run before it (May 6 to May 27) is when to open; the hollow amber run after is when to close, with September 29 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
