Gastonia Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Gastonia 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.
The bar compresses Gastonia's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 23–April 13 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 30. Wherever the today marker sits, the nearest color change is your next appointment.
The Gastonia pool calendar
Opening — target March 30
Open by March 30 — a two-week head start on the April 13 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 30
Hold the cover until October 20, then winterize by October 30, a week ahead of the November 9 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Gastonia'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 43° | 43° | 49° | 58° | 66° | 74° | 80° | 80° | 77° | 68° | 57° | 48° |
Warmest water typically July–August (peaking near 80°F); heaters and covers shift any month up.
