Edmond Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Edmond'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.
Edmond, OK — 130 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Edmond's swim season; the hollow teal run before it (March 31 to April 21) is when to open; the hollow amber run after is when to close, with October 29 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Edmond pool calendar
Opening — target April 7
Open by April 7 — a two-week head start on the April 21 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 29
The window opens October 19 once water leaves the algae zone; the model deadline is October 29, a week ahead of the November 5 freeze normal.
Estimated water temperature by month
This is Edmond'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 39° | 41° | 48° | 57° | 64° | 74° | 80° | 82° | 77° | 68° | 56° | 45° |
Warmest water typically July–August (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Broken Arrow's pool season and Lawton's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Oklahoma season index.
Edmond pool season FAQ
When should I open my pool in Edmond, OK?
Open by April 7 — the model places Edmond's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Edmond opening guide has the 12-step sequence.
When should I close my pool in Edmond?
Close by October 29: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Edmond closing guide sequences the work backward from that date.
How long is the swim season in Edmond?
Edmond averages 130 days a year with normal highs of 80°F or better — right on the statewide median. The Oklahoma season index ranks all 6 covered cities by the same metric.
How warm does pool water get in Edmond?
An unheated pool near Edmond typically peaks around 83°F in high summer and bottoms out near 39°F in winter, spending roughly 2 months at or above the 78°F comfort line most swimmers prefer. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
