Last updated: July 15, 2026 · dates · water temp

This is the one-page view of St. Cloud's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.

The bar compresses St. Cloud's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the January 12–February 2 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends December 30. Wherever the today marker sits, the nearest color change is your next appointment.
