Spring Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Spring'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 Spring's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 10–March 3 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 28. Wherever the today marker sits, the nearest color change is your next appointment.
The Spring pool calendar
Opening — target February 17
Open by February 17 — a two-week head start on the March 3 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 28
The window opens November 18 once water leaves the algae zone; the model deadline is November 28, a week ahead of the December 9 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Spring'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 54° | 55° | 61° | 67° | 74° | 81° | 84° | 86° | 83° | 76° | 66° | 58° |
Warmest water typically June–September (peaking near 86°F); heaters and covers shift any month up.
