Newark Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Newark'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 Newark's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 19–May 10 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 15. Wherever the today marker sits, the nearest color change is your next appointment.
The Newark pool calendar
Opening — target April 26
Open by April 26 — a two-week head start on the May 10 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 15
The window opens October 5 once water leaves the algae zone; the model deadline is October 15, a week ahead of the November 6 freeze normal.
Estimated water temperature by month
This is Newark'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 34° | 33° | 38° | 47° | 58° | 68° | 76° | 77° | 73° | 63° | 51° | 41° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
