Last updated: July 25, 2026 · dates · water temp

One bar, one year, one Alexandria 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.

The bar compresses Alexandria's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 3–March 24 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 13. Wherever the today marker sits, the nearest color change is your next appointment.

Opening — target March 10

Open by March 10 — a two-week head start on the March 24 crossing keeps startup chemistry small and beats the local service rush.

Closing — deadline November 13

The window opens November 3 once water leaves the algae zone; the model deadline is November 13, a week ahead of the November 27 freeze normal.

Monthly averages of the site's water model run on Alexandria's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.

Every station tells its own story: compare this curve with Slidell's pool season and Baton Rouge's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Louisiana season index.

Alexandria pool season FAQ

When should I open my pool in Alexandria, LA?

Open by March 10 — the model places Alexandria's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Alexandria opening guide has the 12-step sequence.

When should I close my pool in Alexandria?

Close by November 13: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Alexandria closing guide sequences the work backward from that date.

How long is the swim season in Alexandria?

Alexandria averages 163 days a year with normal highs of 80°F or better — about 7 days later than the Louisiana median. The Louisiana season index ranks all 13 covered cities by the same metric.

How warm does pool water get in Alexandria?

An unheated pool near Alexandria typically peaks around 83°F in high summer and bottoms out near 48°F in winter, spending roughly 3 months at or above the 78°F comfort line most swimmers prefer. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
