Cedar Park Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Cedar Park pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Cedar Park's swim season; the hollow teal run before it (February 28 to March 21) is when to open; the hollow amber run after is when to close, with November 13 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Cedar Park pool calendar
Opening — target March 7
Open by March 7 — a two-week head start on the March 21 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 13
The window opens November 5 once water leaves the algae zone; the model deadline is November 13, a week ahead of the November 20 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Cedar 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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 51° | 57° | 64° | 70° | 79° | 83° | 85° | 81° | 74° | 63° | 53° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
