Monroe Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Monroe'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.
The bar compresses Monroe's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 7–March 28 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 8. Wherever the today marker sits, the nearest color change is your next appointment.
The Monroe pool calendar
Opening — target March 14
Open by March 14 — a two-week head start on the March 28 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 8
The window opens October 29 once water leaves the algae zone; the model deadline is November 8, a week ahead of the November 15 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Monroe's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 47° | 48° | 55° | 62° | 70° | 78° | 82° | 83° | 80° | 72° | 60° | 52° |
Warmest water typically June–September (peaking near 83°F); heaters and covers shift any month up.
