Roanoke Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Roanoke's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Each dot on the bar is one week of Roanoke's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (April 5–April 26), solid teal is swim season, and hollow amber is the closing window ending October 20. The black marker is today — its position against the colors is the entire executive summary.
The Roanoke pool calendar
Opening — target April 12
Open by April 12 — a two-week head start on the April 26 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 20
The window opens October 10 once water leaves the algae zone; the model deadline is October 20, a week ahead of the November 1 freeze normal.
Estimated water temperature by month
This is Roanoke'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 39° | 39° | 45° | 54° | 63° | 70° | 77° | 77° | 73° | 64° | 53° | 44° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
