Reading 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 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.
