Memphis Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Memphis pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
Memphis, TN — 147 swim days a yearEach dot on the bar is one week of Memphis's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (March 18–April 8), solid teal is swim season, and hollow amber is the closing window ending November 3. The black marker is today — its position against the colors is the entire executive summary.
The Memphis pool calendar
Opening — target March 25
Open by March 25 — a two-week head start on the April 8 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 3
Hold the cover until October 24, then winterize by November 3, a week ahead of the November 16 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Memphis'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 43° | 44° | 50° | 59° | 68° | 77° | 82° | 83° | 80° | 70° | 58° | 48° |
Warmest water typically July–September (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Knoxville's pool season and Morristown's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Tennessee season index.
