Lakewood Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Lakewood'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.
The bar compresses Lakewood's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 9–March 30 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 29. Wherever the today marker sits, the nearest color change is your next appointment.
The Lakewood pool calendar
Opening — target March 16
Target March 16; the practical window runs March 9–March 30, and the 7-day mean crosses the 61°F threshold around March 30. Cold-water starts are the cheap ones.
Closing — deadline November 29
The window opens November 19 once water leaves the algae zone; the model deadline is November 29, a week ahead of the January 5 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Lakewood'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° | 57° | 59° | 61° | 64° | 67° | 71° | 74° | 74° | 71° | 65° | 58° |
The curve peaks near 74°F — comfortable-water months here usually involve a heater or a solar cover.
