Scranton Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Scranton'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 Scranton'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 25–May 16), solid teal is swim season, and hollow amber is the closing window ending October 5. The black marker is today — its position against the colors is the entire executive summary.
The Scranton pool calendar
Opening — target May 2
Target May 2; the practical window runs April 25–May 16, and the 7-day mean crosses the 61°F threshold around May 16. Cold-water starts are the cheap ones.
Closing — deadline October 5
Hold the cover until September 25, then winterize by October 5, a week ahead of the October 20 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Scranton'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 30° | 28° | 34° | 45° | 57° | 65° | 72° | 73° | 69° | 59° | 48° | 38° |
The curve peaks near 74°F — comfortable-water months here usually involve a heater or a solar cover.
