South Jordan Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of South Jordan'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.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is South Jordan's swim season; the hollow teal run before it (April 24 to May 15) is when to open; the hollow amber run after is when to close, with October 10 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The South Jordan pool calendar
Opening — target May 1
Target May 1; the practical window runs April 24–May 15, and the 7-day mean crosses the 61°F threshold around May 15. Cold-water starts are the cheap ones.
Closing — deadline October 10
Hold the cover until September 30, then winterize by October 10, a week ahead of the October 22 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is South Jordan's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 32° | 34° | 42° | 49° | 56° | 67° | 76° | 80° | 73° | 61° | 48° | 36° |
Warmest water typically August–August (peaking near 81°F); heaters and covers shift any month up.
