Baldwin Park Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Baldwin Park'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 Baldwin Park's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 25–March 18 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 30. Wherever the today marker sits, the nearest color change is your next appointment.
The Baldwin Park pool calendar
Opening — target March 4
Target March 4; the practical window runs February 25–March 18, and the 7-day mean crosses the 61°F threshold around March 18. Cold-water starts are the cheap ones.
Closing — deadline November 30
Hold the cover until November 20, then winterize by November 30, a week ahead of the January 2 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Baldwin 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° | 57° | 59° | 62° | 65° | 69° | 74° | 76° | 77° | 72° | 66° | 58° |
The curve peaks near 77°F — comfortable-water months here usually involve a heater or a solar cover.
