Greensboro Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Greensboro 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 Greensboro's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 30–April 20 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 24. Wherever the today marker sits, the nearest color change is your next appointment.
The Greensboro pool calendar
Opening — target April 6
Open by April 6 — a two-week head start on the April 20 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 24
Hold the cover until October 14, then winterize by October 24, a week ahead of the November 4 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Greensboro'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 40° | 41° | 47° | 56° | 65° | 72° | 78° | 79° | 74° | 66° | 54° | 46° |
Warmest water typically July–August (peaking near 80°F); heaters and covers shift any month up.
