Prescott Valley Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Prescott Valley'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 Prescott Valley's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (April 27–May 18), solid teal is swim season, and hollow amber is the closing window ending October 13. The black marker is today — its position against the colors is the entire executive summary.
The Prescott Valley pool calendar
Opening — target May 4
Target May 4; the practical window runs April 27–May 18, and the 7-day mean crosses the 61°F threshold around May 18. Cold-water starts are the cheap ones.
Closing — deadline October 13
Hold the cover until October 3, then winterize by October 13, 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 Prescott Valley'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 38° | 39° | 44° | 50° | 57° | 66° | 74° | 75° | 71° | 62° | 51° | 41° |
The curve peaks near 75°F — comfortable-water months here usually involve a heater or a solar cover.
