Hickory Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Hickory 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.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Hickory's swim season; the hollow teal run before it (April 2 to April 23) is when to open; the hollow amber run after is when to close, with October 21 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Hickory pool calendar
Opening — target April 9
Open by April 9 — a two-week head start on the April 23 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 21
Hold the cover until October 11, then winterize by October 21, a week ahead of the November 4 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Hickory'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° | 55° | 63° | 71° | 77° | 77° | 74° | 65° | 54° | 45° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
