The Kenner 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
Hold the cover until November 20, then winterize by November 30, a week ahead of the December 31 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Kenner's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| 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 Houma's pool season and Lafayette's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Louisiana season index.
