Concord Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Concord 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.
Concord, NC — 144 swim days a yearThe bar compresses Concord's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 28–April 18 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 26. Wherever the today marker sits, the nearest color change is your next appointment.
The Concord pool calendar
Opening — target April 4
Open by April 4 — a two-week head start on the April 18 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 26
Hold the cover until October 16, then winterize by October 26, a week ahead of the November 2 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Concord'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 42° | 42° | 48° | 56° | 65° | 73° | 79° | 80° | 76° | 67° | 55° | 47° |
Warmest water typically July–August (peaking near 80°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Charlotte's pool season and Durham's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the North Carolina season index.

When should I close my pool in Concord?
Winterize by October 26. The model holds the deadline a week ahead of Concord's NOAA 50% first-freeze date, so the plumbing is protected before the first hard night. The full sequence is in the Concord closing guide.
