West Jordan Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one West Jordan pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
West Jordan, UT — 113 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is West 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 West Jordan pool calendar
Opening — target May 1
Open by May 1 — a two-week head start on the May 15 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 10
The window opens September 30 once water leaves the algae zone; the model deadline is October 10, a week ahead of the October 22 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on West Jordan's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| 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.
Every station tells its own story: compare this curve with St. George's pool season and West Valley City's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Utah season index.
