Vineland Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Vineland'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 Vineland's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 23–May 14 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 13. Wherever the today marker sits, the nearest color change is your next appointment.
The Vineland pool calendar
Opening — target April 30
Target April 30; the practical window runs April 23–May 14, and the 7-day mean crosses the 61°F threshold around May 14. Cold-water starts are the cheap ones.
Closing — deadline October 13
Hold the cover until October 3, then winterize by October 13, a week ahead of the October 23 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Vineland's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 35° | 33° | 38° | 48° | 58° | 67° | 75° | 76° | 72° | 62° | 50° | 41° |
The curve peaks near 76°F — comfortable-water months here usually involve a heater or a solar cover.
