Layton Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Layton 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.
Layton, UT — 86 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Layton's swim season; the hollow teal run before it (May 10 to May 31) is when to open; the hollow amber run after is when to close, with October 4 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Layton pool calendar
Opening — target May 17
Open by May 17 — a two-week head start on the May 31 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 4
Hold the cover until September 24, then winterize by October 4, a week ahead of the October 20 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Layton'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 27° | 30° | 38° | 44° | 53° | 62° | 73° | 77° | 69° | 58° | 45° | 32° |
The curve peaks near 79°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with West Valley City's pool season and Lehi's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Utah season index.
Layton pool season FAQ
When should I open my pool in Layton, UT?
Target May 17. That date backs off two weeks from the day Layton's 7-day mean temperature reaches 61°F, so you start up in cold, algae-resistant water. Work the full checklist in the Layton opening guide.
When should I close my pool in Layton?
The closing deadline is October 4 — late enough that the water has cooled out of the algae zone, early enough to beat Layton's first-freeze normal by about a week. See the Layton closing guide for the winterizing steps.
How long is the swim season in Layton?
Layton averages 86 days a year with normal highs of 80°F or better — about 15 days later than the Utah median. The Utah season index ranks all 12 covered cities by the same metric.
How warm does pool water get in Layton?
An unheated pool near Layton typically peaks around 79°F in high summer and bottoms out near 27°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
