Suffolk Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Suffolk'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 Suffolk'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 3–April 24), solid teal is swim season, and hollow amber is the closing window ending October 26. The black marker is today — its position against the colors is the entire executive summary.
The Suffolk pool calendar
Opening — target April 10
Target April 10; the practical window runs April 3–April 24, and the 7-day mean crosses the 61°F threshold around April 24. Cold-water starts are the cheap ones.
Closing — deadline October 26
Hold the cover until October 16, then winterize by October 26, a week ahead of the November 15 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Suffolk'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 41° | 41° | 46° | 54° | 63° | 71° | 77° | 78° | 74° | 66° | 55° | 47° |
Warmest water typically August–August (peaking near 78°F); heaters and covers shift any month up.
