Hoover Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Hoover'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.
Each dot on the bar is one week of Hoover's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (March 14–April 4), solid teal is swim season, and hollow amber is the closing window ending November 1. The black marker is today — its position against the colors is the entire executive summary.
The Hoover pool calendar
Opening — target March 21
Open by March 21 — a two-week head start on the April 4 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 1
The window opens October 23 once water leaves the algae zone; the model deadline is November 1, a week ahead of the November 8 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Hoover'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 45° | 46° | 53° | 61° | 68° | 76° | 81° | 82° | 79° | 70° | 58° | 50° |
Warmest water typically July–September (peaking near 82°F); heaters and covers shift any month up.
