Independence Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Independence'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.
Independence, MO — 101 swim days a yearThe bar compresses Independence's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 18–May 9 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 13. Wherever the today marker sits, the nearest color change is your next appointment.
The Independence pool calendar
Opening — target April 25
Open by April 25 — a two-week head start on the May 9 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 13
Hold the cover until October 3, then winterize by October 13, a week ahead of the October 27 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Independence's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 30° | 30° | 39° | 49° | 59° | 70° | 76° | 77° | 72° | 62° | 49° | 38° |
The curve peaks near 78°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with Columbia's pool season and Joplin's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Missouri season index.
Independence pool season FAQ
When should I open my pool in Independence, MO?
Open by April 25 — the model places Independence's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Independence opening guide has the 12-step sequence.
When should I close my pool in Independence?
Close by October 13: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Independence closing guide sequences the work backward from that date.
How long is the swim season in Independence?
Independence averages 101 days a year with normal highs of 80°F or better — about 7 days later than the Missouri median. The Missouri season index ranks all 8 covered cities by the same metric.
How warm does pool water get in Independence?
An unheated pool near Independence typically peaks around 78°F in high summer and bottoms out near 28°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
