Shreveport Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Shreveport's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Shreveport, LA — 170 swim days a yearEach 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 Shreveport pool calendar
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 11
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.
Estimated water temperature by month
This is Shreveport'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 49° | 56° | 63° | 70° | 78° | 83° | 84° | 82° | 73° | 61° | 52° |
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 New Orleans's pool season and Slidell's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Louisiana season index.
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.
