Houma Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
Houma's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Houma, LA — 181 swim days a yearThe bar compresses Houma's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 10–March 3 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 28. Wherever the today marker sits, the nearest color change is your next appointment.
The Houma pool calendar
Opening — target February 17
Open by February 17 — a two-week head start on the March 3 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 28
The window opens November 18 once water leaves the algae zone; the model deadline is November 28, a week ahead of the December 17 freeze normal.
Estimated water temperature by month
This is Houma'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 54° | 55° | 61° | 66° | 73° | 80° | 82° | 83° | 82° | 76° | 66° | 59° |
Warmest water typically June–September (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Hammond's pool season and Kenner's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Louisiana season index.
Houma pool season FAQ
When should I open my pool in Houma, LA?
Open by February 17 — the model places Houma's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Houma opening guide has the 12-step sequence.
When should I close my pool in Houma?
Close by November 28: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Houma closing guide sequences the work backward from that date.
How long is the swim season in Houma?
Houma averages 181 days a year with normal highs of 80°F or better — about 14 days earlier than the Louisiana median. The Louisiana season index ranks all 13 covered cities by the same metric.
How warm does pool water get in Houma?
An unheated pool near Houma typically peaks around 83°F in high summer and bottoms out near 54°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.
