Lafayette Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Lafayette 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.
Each dot on the bar is one week of Lafayette's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (February 21–March 14), solid teal is swim season, and hollow amber is the closing window ending November 20. The black marker is today — its position against the colors is the entire executive summary.
The Lafayette pool calendar
Opening — target February 28
Open by February 28 — a two-week head start on the March 14 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 20
The window opens November 10 once water leaves the algae zone; the model deadline is November 20, a week ahead of the November 28 freeze normal.
Estimated water temperature by month
This is Lafayette'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 52° | 53° | 59° | 65° | 72° | 79° | 82° | 82° | 81° | 74° | 64° | 56° |
Warmest water typically June–September (peaking near 82°F); heaters and covers shift any month up.
