Glendale Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Glendale's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Glendale's swim season; the hollow teal run before it (March 18 to April 8) is when to open; the hollow amber run after is when to close, with November 23 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Glendale pool calendar
Opening — target March 25
Target March 25; the practical window runs March 18–April 8, and the 7-day mean crosses the 61°F threshold around April 8. Cold-water starts are the cheap ones.
Closing — deadline November 23
Hold the cover until November 13, then winterize by November 23, a week ahead of the December 26 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Glendale'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 55° | 56° | 58° | 61° | 64° | 67° | 72° | 75° | 75° | 71° | 64° | 57° |
The curve peaks near 76°F — comfortable-water months here usually involve a heater or a solar cover.
