Last updated: July 25, 2026 · dates · water temp
Metairie'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.
Metairie, LA — 179 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is Metairie's swim season; the hollow teal run before it (February 9 to March 2) is when to open; the hollow amber run after is when to close, with November 30 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Metairie pool calendar
Opening — target February 16
Target February 16; the practical window runs February 9–March 2, and the 7-day mean crosses the 61°F threshold around March 2. Cold-water starts are the cheap ones.
Closing — deadline November 30
The window opens November 20 once water leaves the algae zone; the model deadline is November 30, a week ahead of the December 31 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Metairie'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 55° | 56° | 61° | 67° | 74° | 80° | 83° | 84° | 83° | 77° | 67° | 59° |
Warmest water typically June–September (peaking near 84°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Mandeville's pool season and Monroe's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Louisiana season index.
