Paradise Pool Season: the Year on One Bar

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

This is the one-page view of Paradise'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.

Each dot on the bar is one week of Paradise's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (February 24–March 17), solid teal is swim season, and hollow amber is the closing window ending November 16. The black marker is today — its position against the colors is the entire executive summary.
