Reading 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.

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.
