Each dot on the bar is one week of Shreveport'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 3–March 24), solid teal is swim season, and hollow amber is the closing window ending November 11. The black marker is today — its position against the colors is the entire executive summary.

The window opens November 1 once water leaves the algae zone; the model deadline is November 11, a week ahead of the November 18 freeze normal.

Shreveport pool season FAQ

When should I open my pool in Shreveport, LA?

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

When should I close my pool in Shreveport?

Close by November 11: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Shreveport closing guide sequences the work backward from that date.

How long is the swim season in Shreveport?

Shreveport averages 170 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 Shreveport?

An unheated pool near Shreveport typically peaks around 84°F in high summer and bottoms out near 48°F in winter, spending roughly 4 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.
