Elizabeth Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Elizabeth pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
Elizabeth, NJ — 92 swim days a yearEach dot on the bar is one week of Elizabeth's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (April 18–May 9), solid teal is swim season, and hollow amber is the closing window ending October 16. The black marker is today — its position against the colors is the entire executive summary.
The Elizabeth pool calendar
Opening — target April 25
Target April 25; the practical window runs April 18–May 9, and the 7-day mean crosses the 61°F threshold around May 9. Cold-water starts are the cheap ones.
Closing — deadline October 16
The window opens October 6 once water leaves the algae zone; the model deadline is October 16, a week ahead of the November 10 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Elizabeth'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 35° | 33° | 39° | 48° | 59° | 68° | 77° | 78° | 73° | 63° | 52° | 42° |
Warmest water typically August–August (peaking near 78°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Clifton's pool season and Jersey City's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the New Jersey season index.
Elizabeth pool season FAQ
When should I open my pool in Elizabeth, NJ?
Open by April 25 — the model places Elizabeth's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Elizabeth opening guide has the 12-step sequence.
When should I close my pool in Elizabeth?
Close by October 16: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Elizabeth closing guide sequences the work backward from that date.
How long is the swim season in Elizabeth?
Elizabeth averages 92 days a year with normal highs of 80°F or better — about 5 days earlier than the New Jersey median. The New Jersey season index ranks all 7 covered cities by the same metric.
How warm does pool water get in Elizabeth?
An unheated pool near Elizabeth typically peaks around 78°F in high summer and bottoms out near 32°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
