Salem Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Salem's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Salem's swim season; the hollow teal run before it (May 17 to June 7) is when to open; the hollow amber run after is when to close, with October 6 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Salem pool calendar
Opening — target May 24
Target May 24; the practical window runs May 17–June 7, and the 7-day mean crosses the 61°F threshold around June 7. Cold-water starts are the cheap ones.
Closing — deadline October 6
Hold the cover until September 26, then winterize by October 6, a week ahead of the November 1 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Salem'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° | 43° | 46° | 49° | 55° | 60° | 67° | 70° | 67° | 59° | 50° | 43° |
The curve peaks near 70°F — comfortable-water months here usually involve a heater or a solar cover.
