Canton Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
Canton's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Canton, OH — 82 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Canton's swim season; the hollow teal run before it (April 24 to May 15) is when to open; the hollow amber run after is when to close, with October 7 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Canton pool calendar
Opening — target May 1
Open by May 1 — a two-week head start on the May 15 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 7
The window opens September 27 once water leaves the algae zone; the model deadline is October 7, a week ahead of the October 26 freeze normal.
Estimated water temperature by month
This is Canton'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 30° | 28° | 35° | 46° | 57° | 66° | 73° | 73° | 69° | 59° | 48° | 37° |
The curve peaks near 74°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with Akron's pool season and Cincinnati's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Ohio season index.
Canton pool season FAQ
When should I open my pool in Canton, OH?
Open by May 1 — the model places Canton's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Canton opening guide has the 12-step sequence.
When should I close my pool in Canton?
Close by October 7: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Canton closing guide sequences the work backward from that date.
How long is the swim season in Canton?
Canton averages 82 days a year with normal highs of 80°F or better — right on the statewide median. The Ohio season index ranks all 14 covered cities by the same metric.
How warm does pool water get in Canton?
An unheated pool near Canton typically peaks around 74°F in high summer and bottoms out near 28°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.
