Springdale Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Springdale'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 Springdale'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 6–April 27), solid teal is swim season, and hollow amber is the closing window ending October 21. The black marker is today — its position against the colors is the entire executive summary.
The Springdale pool calendar
Opening — target April 13
Open by April 13 — a two-week head start on the April 27 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 21
The window opens October 11 once water leaves the algae zone; the model deadline is October 21, a week ahead of the October 31 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Springdale'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 37° | 38° | 45° | 54° | 62° | 71° | 78° | 79° | 75° | 65° | 53° | 43° |
Warmest water typically July–August (peaking near 79°F); heaters and covers shift any month up.
