Lehi Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Lehi's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
The bar compresses Lehi's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the May 6–May 27 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends September 30. Wherever the today marker sits, the nearest color change is your next appointment.
The Lehi pool calendar
Opening — target May 13
Target May 13; the practical window runs May 6–May 27, and the 7-day mean crosses the 61°F threshold around May 27. Cold-water starts are the cheap ones.
Closing — deadline September 30
Hold the cover until September 20, then winterize by September 30, a week ahead of the October 9 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Lehi'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 28° | 31° | 39° | 46° | 53° | 63° | 72° | 76° | 68° | 57° | 44° | 33° |
The curve peaks near 77°F — comfortable-water months here usually involve a heater or a solar cover.
