Orange Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Orange'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 Orange's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 8–March 1 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends December 10. Wherever the today marker sits, the nearest color change is your next appointment.
The Orange pool calendar
Opening — target February 15
Target February 15; the practical window runs February 8–March 1, and the 7-day mean crosses the 61°F threshold around March 1. Cold-water starts are the cheap ones.
Closing — deadline December 10
Hold the cover until November 30, then winterize by December 10, a week ahead of the December 25 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Orange'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 60° | 60° | 61° | 64° | 67° | 70° | 74° | 77° | 77° | 74° | 68° | 61° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
