Johns Creek Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Johns Creek 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.
Johns Creek, GA — 135 swim days a yearThe bar compresses Johns Creek's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 26–April 16 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 27. Wherever the today marker sits, the nearest color change is your next appointment.
The Johns Creek pool calendar
Opening — target April 2
Open by April 2 — a two-week head start on the April 16 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 27
Hold the cover until October 17, then winterize by October 27, a week ahead of the November 9 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Johns Creek'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 43° | 44° | 50° | 58° | 66° | 74° | 78° | 80° | 76° | 68° | 56° | 48° |
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 Gainesville's pool season and Mableton's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Georgia season index.
