Buena Park Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Buena Park'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 Buena Park's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (February 20–March 13), solid teal is swim season, and hollow amber is the closing window ending November 30. The black marker is today — its position against the colors is the entire executive summary.
The Buena Park pool calendar
Opening — target February 27
Target February 27; the practical window runs February 20–March 13, and the 7-day mean crosses the 61°F threshold around March 13. Cold-water starts are the cheap ones.
Closing — deadline November 30
The window opens November 20 once water leaves the algae zone; the model deadline is November 30, a week ahead of the January 2 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Buena Park'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 57° | 58° | 60° | 63° | 66° | 69° | 74° | 76° | 76° | 72° | 66° | 59° |
The curve peaks near 77°F — comfortable-water months here usually involve a heater or a solar cover.
